98-1062TRPBF Overview
A power-factor-correction controller is a semiconductor used in AC-to-DC power supplies to reduce reactive current and improve the input power factor. In a boost-type PFC stage, the controller regulates the switching converter so that the input current follows the input-voltage waveform, rather than drawing narrow, pulsed current from the rectified line. One-cycle control indicates a control architecture intended to respond within the switching cycle; exact implementation details and compensation requirements require confirmation in the manufacturer datasheet. This topology is commonly associated with switch-mode power supplies, industrial power systems, and equipment that reduces line-current distortion.
The verified product information confirms the Infineon brand, PFC-controller function, one-cycle control classification, and 8SOIC package. It does not provide verified values for input-voltage range, output-voltage range, maximum switching frequency, duty-cycle range, gate-drive voltage, quiescent current, operating temperature, thermal resistance, RoHS status, REACH status, or automotive qualification. Those values are not inferred here because doing so would create unsupported engineering specifications. The practical design process should begin with the official Infineon datasheet, followed by validation of line transients, inductor selection, current-sense limits, startup behavior, fault response, and thermal performance in the target enclosure.
The 8SOIC package is relevant to PCB layout because its lead pitch and land pattern must be matched by the board footprint. Although the package is surface mount, proper trace spacing, creepage, isolation, and thermal layout remain application-dependent. The controller may be used near a high-voltage rectified bus, so the exact clearances and protection network should be established from the relevant safety requirements and the final operating voltage.
Potential applications include PFC front ends for industrial AC-DC supplies, server or telecom power-supply modules, charger power stages, and other line-powered equipment where input-current harmonics and power factor are important. These are functional use cases rather than claims that every variant is qualified for every product. The actual selection requires confirmation of voltage ratings, switching capability, control compatibility, and thermal limits.
The most important design check is the compatibility between the controller, boost inductor, switching device, current-sense network, output bus capacitor, and feedback loop. A valid design must maintain the required duty-cycle and current margins across the complete mains range, including line transients and startup. The one-cycle label alone is not enough to establish performance; use the manufacturer application guidance and measured prototype results.
This page combines the verified distributor identity, package description, and sourcing information with explicit data gaps and practical engineering guidance. It is intended to support component identification and preliminary design planning, not to replace the manufacturer datasheet, cross-reference verification, or application-specific safety review.

Typical Applications
98-1062TRPBF is suitable for 6 applications: Industrial AC-DC PFC Front End, Server Power-Supply PFC Stage, Telecom Power Module, Battery Charger Input Stage, Line-Powered Industrial Charger, Power-Supply Reference Design.
Industrial AC-DC PFC Front End
98-1062TRPBF can be evaluated for an industrial AC-DC power-conversion front end when the designer confirms that its one-cycle PFC control matches the required line-current waveform and correction strategy. The controller belongs in the control section of a boost-type PFC stage, where it coordinates the switching device and current regulation to reduce input distortion. The 8SOIC package supports conventional surface-mount PCB assembly, but the exact voltage, current, duty-cycle, and protection ratings are not present in the supplied data. Those ratings must be checked against the industrial input range, surge environment, startup sequence, and required power factor before committing to the design.
Recommended
Server Power-Supply PFC Stage
The one-cycle PFC controller classification makes 98-1062TRPBF a candidate for investigation in server or telecom power-supply front ends where input-current harmonics and power factor are important. Such systems typically require precise current shaping, fault handling, and reliable operation across changing line conditions. The supplied data does not establish whether the controller meets a particular server power-supply specification, efficiency target, or safety requirement. Designers should compare the verified datasheet limits with the target bus voltage, switching device, inductor, current-sense network, and thermal budget, then validate conducted emissions and line transient behavior before production use.
Recommended
Telecom Power Module
98-1062TRPBF may be considered for a telecom-oriented power module that includes an active PFC stage to improve the relationship between AC input current and input voltage. Telecom equipment can require low input distortion, controlled startup, and dependable operation over a broad external supply range. Since the verified data identifies only the PFC function, one-cycle control, manufacturer, and 8SOIC package, it does not prove compliance with any telecom-specific qualification or emissions requirement. The correct design process is to verify operating limits and protection thresholds, complete isolation and clearance review, and test the assembled module with representative mains conditions and switching-node measurements.
Recommended
Battery Charger Input Stage
A battery-charging system may use 98-1062TRPBF in its upstream AC input correction stage before energy is transferred to a battery-management circuit. Active PFC can reduce reactive current and improve the power factor seen by the upstream AC supply, while the downstream converter manages battery charging current and voltage. The supplied information does not provide the controller's charging-specific limits, so it must not be assumed to regulate battery voltage directly or to provide charger protection. Confirm the PFC operating envelope, feedback interface, current-sense implementation, and fault behavior against the charger architecture and applicable safety requirements.
Recommended
Line-Powered Industrial Charger
For a line-powered industrial charger, 98-1062TRPBF is a possible PFC front-end candidate if its verified control characteristics support the required input-current profile. The controller can help shape current drawn from the rectified mains before downstream power conversion, but the design still needs appropriate boost inductance, switching-device selection, bus capacitors, sensing, and protection. The verified data does not identify maximum current, switching frequency, startup timing, or fault thresholds. Engineers should therefore obtain the manufacturer documentation, calculate worst-case component stresses, verify PCB creepage and isolation, and test the charger across nominal and transient line conditions.
Recommended
Power-Supply Reference Design
98-1062TRPBF can serve as the basis for a controlled PFC experiment or power-supply reference design when engineers need to evaluate one-cycle control behavior in an accessible SOIC package. The eight-lead surface-mount format is useful for creating a compact prototype, but the actual pinout and electrical thresholds must come from the official datasheet. A successful reference design requires measuring input current shape, output-bus ripple, switch-node voltage, inductor current, startup behavior, and fault response. The supplied web data does not include a manufacturer reference circuit, so the design should be treated as exploratory until the relevant application guidance is located and validated.

Design Notes
Do not select the inductor, switch, current-sense resistor, or bus capacitor from the product description alone. First obtain the verified 98-1062TRPBF voltage, duty-cycle, current-limit, and timing limits, then calculate worst-case stresses across the complete mains range. In a boost PFC stage, the switch and inductor experience voltage and current transients that may exceed nominal values, so component ratings should include the required design margin.
Keep the controller's power and signal connections short, and place input, feedback, current-sense, and gate-drive decoupling according to the manufacturer layout guidance. The SOIC footprint alone does not establish high-voltage safety. Review creepage, clearance, isolation barriers, and the separation between the switching node and sensitive current-sense or feedback paths before fabrication.
Do not use the phrase one-cycle control as a substitute for a verified timing and feedback design. Confirm the controller's control-loop requirements, current-sense polarity and threshold, startup behavior, fault response, and pin functions from the Infineon datasheet. Guessing an 8SOIC pinout or assuming a generic PFC application circuit can produce incorrect switching, unsafe voltage exposure, or unstable bus regulation.
Compliance Information
The supplied verified web data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for 98-1062TRPBF. Obtain the current manufacturer declaration or exact distributor documentation.
