ICE3RBR0665JZXKLA1 Overview
A current-mode PWM controller is a control IC that regulates output by sensing the current through the main power switch on a cycle-by-cycle basis, providing inherent peak-current limiting and simplified loop compensation. Within the broader taxonomy, an SMPS controller falls under AC-DC converters -> power management IC -> semiconductor. The CoolSET family further integrates the high-voltage MOSFET into the same package, which makes it distinct from controllers that require an external FET and from fully integrated modules.
Key features of the ICE3RBR0665JZXKLA1 include a 650V integrated CoolMOS with a maximum on-resistance per the CoolSET F3R family datasheet, a 65 kHz fixed switching frequency, auto-restart protection for open-loop, VCC overvoltage, and overload faults, and an extended operating temperature range down to -40C. According to the manufacturer datasheet, the VCC supply range is 10.5V to 25V and the duty cycle maximum is 75%, supporting compact adapter and auxiliary-supply designs.
Typical applications include low-power AC/DC adapters (smartphone chargers, set-top boxes, DVD players), standby and auxiliary supplies for white goods and industrial equipment, and isolated auxiliary rails in motor drives and metered appliances. The integrated start-up cell eliminates external bleeder resistors and reduces standby power, while the integrated 650V switch withstands universal mains transients.
When designing with this part, designers must observe the VCC start-up threshold (18V typical) and select a VCC hold-up capacitor sized for the desired burst-mode entry threshold. The PG-DIP-7-1 package provides adequate creepage for reinforced isolation when paired with a through-hole transformer construction. Designers should follow the Infineon CoolSET design guide for snubber and RCD clamp values.

Typical Applications
ICE3RBR0665JZXKLA1 is suitable for 7 applications: Smartphone / Tablet Wall Adapters, Set-Top Box and DVD Player Power Supplies, White Goods Auxiliary / Standby Supplies, Industrial Auxiliary Power Supplies, LED Lighting Drivers (Isolated), Metered Appliance and Smart-Home Hub Supplies, Universal-Input Battery Chargers.
Smartphone / Tablet Wall Adapters
The ICE3RBR0665JZXKLA1 fits 5W to 41W universal-input flyback adapters because its 650V integrated CoolMOS tolerates 265VAC rectified peaks, and the 65 kHz fixed frequency gives predictable EMI filter design. The integrated start-up cell drops standby below 100mW in 5V/2A chargers, and the auto-restart protection handles open-loop, VCC-OV, and overload faults without external supervisor parts. Used downstream of a bridge rectifier and bulk cap, the IC drives a small EE16/EE19 transformer with 1.5 to 2.0 mm creepage for IEC 62368-1 reinforced insulation, and the PG-DIP-7-1 package mates naturally with through-hole transformer winding. For higher-power designs above 25W, choose a CoolSET variant with lower Rds(on).

Set-Top Box and DVD Player Power Supplies
The ICE3RBR0665JZXKLA1 is a strong match for set-top box and DVD player SMPS in the 10W to 30W range, where its integrated 650V CoolMOS eliminates external MOSFET routing and its 65 kHz fixed frequency simplifies conducted-EMI filter sizing. The current-mode control loop provides cycle-by-cycle current limiting, which is important for the harsh step-load transients of digital TV tuner and hard-disk start-up. With the -40C to +125C operating range, the IC tolerates the closed-cabinet thermal environment of A/V equipment. The 10.5V to 25V VCC range supports a wide hold-up capacitor choice for various hold-up-time requirements. Pair with a TL431 + optocoupler feedback network for primary-side regulation accuracy better than 5%.
Recommended
White Goods Auxiliary / Standby Supplies
The ICE3RBR0665JZXKLA1 powers 3W to 15W standby rails in washing machines, refrigerators, and dishwashers, where its 650V breakdown handles the rectified 230VAC mains plus inductive spike margin, and the integrated start-up cell achieves sub-30mW standby for Energy Star and EU ErP compliance. The auto-restart protection responds to overload and open-loop faults without latching, which is preferred for unattended appliance operation. The PG-DIP-7-1 through-hole package withstands wave-soldering of the main PCB and supports the wide operating-temperature range required for kitchen environments. Use a simple snubber + RCD clamp to keep the drain voltage below 600V under all transient conditions.
Recommended
Industrial Auxiliary Power Supplies
The ICE3RBR0665JZXKLA1 fits isolated 5W to 30W auxiliary rails in industrial PLCs, motor drives, and HMI controllers, where its 650V breakdown handles rectified 3-phase 400VAC or 480VAC industrial mains with adequate margin. The current-mode control simplifies the feedback loop in the presence of noisy industrial environments, and the -40C to +125C operating range supports outdoor and cabinet-mounted installations. The auto-restart fault handling recovers from intermittent shorts on the secondary side, which improves field serviceability. Designers typically use a 10uF to 47uF hold-up capacitor on VCC to meet ride-through requirements during brief brownouts.
Recommended
LED Lighting Drivers (Isolated)
The ICE3RBR0665JZXKLA1 powers isolated 10W to 30W constant-current LED drivers, where its 65 kHz fixed frequency falls outside the audible band and avoids transformer acoustic noise, and its 650V breakdown tolerates 230VAC rectified peaks with surge margin. The current-mode control regulates LED current through a TL431 reference on the secondary side, and the integrated start-up cell keeps standby power low for dimming-off states. The PG-DIP-7-1 package mates with through-hole transformer construction common in linear LED fixtures. Use a Y-class capacitor for primary-secondary coupling to meet IEC 61347-1 reinforced isolation requirements for luminaires.
Recommended
Metered Appliance and Smart-Home Hub Supplies
The ICE3RBR0665JZXKLA1 suits 3W to 20W isolated supplies in smart-home hubs, metered appliances, and IoT gateways, where low standby power and a small footprint are key requirements. The integrated start-up cell enables standby below 50mW to meet Energy Star 8.0, and the 650V integrated CoolMOS eliminates external high-voltage traces for safe consumer installation. The current-mode control supports a wide range of output voltages (3.3V, 5V, 12V) with the same magnetics design. Use the IC with a TLE42744EV50XUMA1 secondary LDO for clean 5V rails powering Wi-Fi/BLE modules.
Recommended
Universal-Input Battery Chargers
The ICE3RBR0665JZXKLA1 powers 5W to 25W universal-input chargers for power tools, e-bikes, and consumer battery packs, where its 650V breakdown handles both 120VAC and 230VAC nominal inputs with surge margin, and its integrated start-up cell provides fast turn-on for plug-in operation. The current-mode control allows tight CC/CV regulation through a TL431 + optocoupler loop, and the auto-restart protection handles output short and overload conditions safely. The PG-DIP-7-1 through-hole package simplifies the mechanical assembly of charger enclosures with cable strain relief. Add a TVS + fuse combination on the input for UL 1310 / IEC 60335 charger safety compliance.

- 65 kHz fixed switching frequency (vs Variable-frequency controllers)
- Auto-restart fault protection (vs Latching protection controllers)
Design Notes
Estimated: Place a 1nF to 4.7nF Y-class safety capacitor between primary and secondary grounds to reduce common-mode EMI while meeting IEC 62368-1 reinforced insulation. Keep the CS-pin sense resistor close to the IC pin (less than 5mm trace) to avoid noise pickup that causes false triggering of the cycle-by-cycle current limit. The DRAIN pin trace should be short and wide to minimize leakage inductance.
Estimated: At 25W output from 230VAC input, the IC dissipates roughly 0.6W to 1.0W depending on Rds(on) and switching losses. The PG-DIP-7-1 package has theta_JA around 80 C/W (free air, no heatsink), yielding a junction rise of 50C to 80C above ambient - within the 125C limit. For sealed enclosures with no airflow, ensure copper-pour area under the IC supports at least 200 sq-mm of 1oz copper to keep junction temperature in spec.
Do not connect the drain snubber RCD clamp across the integrated MOSFET without verifying that the snubber resistor value matches the Infineon CoolSET design guide; undersized resistors cause audible noise and overheating. The VCC hold-up capacitor value sets the burst-mode entry threshold - too-large values delay low-load entry and degrade standby efficiency. Always add a primary-side fuse and TVS for surge protection; the integrated 650V MOSFET alone is not a substitute for external protection in certified designs.
Choose the bulk capacitor after the bridge rectifier based on hold-up time requirement: a 4.7uF to 10uF 400V electrolytic gives roughly 8ms to 10ms hold-up at 12V/2A output from 230VAC. The VCC start-up threshold of 18V and turn-off threshold of around 10V sets a wide hysteresis window, allowing a single 22uF to 47uF VCC cap to cover most hold-up scenarios. Add a 100k bleeder to discharge bulk cap for safety servicing.
