ICE2PCS05GXUMA1 Overview
A PFC controller is a specialized power-supply control IC that forces the input current of an AC-DC converter to follow the sinusoidal line voltage, raising the power factor toward unity and meeting regulatory harmonic standards such as IEC 61000-3-2. In the broader system hierarchy, the PFC stage sits upstream of the main DC-DC converter in switch-mode power supplies; it belongs to the family of AC-DC controllers, which are a subset of power management ICs and ultimately of analog mixed-signal semiconductors.
Key features include a wide VCC operating range of 11 V to 25 V, an internal oscillator with external frequency-setting resistor, average-current control with external loop compensation, and a dedicated bulk-capacitor over-voltage protection (OVP) comparator for direct sensing of the boost output. The IC also provides undervoltage lockout, soft-start, and open-loop/open-frame protection, enabling compliance-mode designs with minimal external parts count. The 8-pin package supports compact, low-cost PFC stages for power supplies up to approximately 300 W.
Typical applications include 80 PLUS-compliant desktop PC and server SMPS front ends, industrial variable-frequency drives and UPS systems, LED lighting drivers with high PF requirements, and white-good appliance power supplies. The wide VCC range and programmable frequency make it well-suited to both cost-sensitive consumer designs and higher-power industrial converters.
When designing with this part, place the current-sense resistor close to the source of the external boost MOSFET to minimize parasitic inductance, and verify that the bulk-cap OVP divider ratio matches your output rail tolerance band.

Typical Applications
ICE2PCS05GXUMA1 is suitable for 6 applications: Desktop PC and Server SMPS Front-End PFC, High-Power LED Lighting Drivers, Industrial Variable-Frequency Drives and UPS, White-Goods Appliance SMPS, Telecom Rectifier Modules, Renewable / Solar Inverter Auxiliary SMPS.
Desktop PC and Server SMPS Front-End PFC
The ICE2PCS05GXUMA1 is the standard 80 PLUS-compliant front-end CCM PFC stage for desktop and entry-server SMPS from roughly 100 W to 300 W. Its 11-25 V VCC range lets the auxiliary winding feed the controller directly across universal 85-265 VAC input, while the 50-250 kHz programmable switching frequency keeps the boost inductor under 500 uH. The 3 V trimmed internal reference provides tight output regulation under line transients, and the bulk-cap OVP comparator protects the downstream 400 V bulk rail if the feedback loop opens. Use it with an external 600 V boost MOSFET and a single current-sense resistor for a complete IEC 61000-3-2 compliant PFC stage.
Recommended
High-Power LED Lighting Drivers
High-bay and street-lighting LED drivers above 75 W commonly require EN 61000-3-2 Class C compliance, which demands active PFC. The ICE2PCS05GXUMA1's average-current control and bulk-cap OVP make it well-suited for 100-200 W constant-current LED driver front ends where bulk-capacitor over-voltage during LED open-circuit events is a real reliability risk. Programming the oscillator to 65-100 kHz balances boost inductor size against switching loss, and the wide VCC range tolerates the wide auxiliary rail variation seen during LED dimming transients. A downstream constant-current controller such as the ILD6150 can then close the LED current loop.
Recommended
Industrial Variable-Frequency Drives and UPS
Three-phase industrial VFD front-ends and on-line UPS rectifiers above 1 kW often begin with a CCM boost PFC stage to meet IEEE 519 and EN 61000-3-12 harmonic limits. The ICE2PCS05GXUMA1 can parallel multiple boost channels with current-share inductors for 1-3 kW applications, and the external loop-compensation lets designers shape the input current for low THD under non-linear load steps typical of motor drives. The 125 C operating junction limit supports sealed enclosure operation common in industrial control cabinets, while the BiCMOS gate driver provides clean switching edges that ease conducted-EMI compliance testing.
Recommended
White-Goods Appliance SMPS
Washing machines, induction cooktops, and dishwasher controllers increasingly integrate switch-mode front-ends to meet EU eco-design standby limits. The ICE2PCS05GXUMA1 fits the 80-200 W universal-input PFC pre-regulator needed in these appliances, with the 8-pin PG-DSO footprint enabling compact PCB layouts inside sealed plastic housings. Its integrated protection features (UVLO, bulk-cap OVP, open-loop protection) reduce external part count and improve field reliability - a key purchasing criterion for consumer appliance OEMs. The -40 C to +125 C operating range also supports unheated garage or basement installations.
Recommended
Telecom Rectifier Modules
48 V telecom rectifier modules typically use a CCM boost PFC front-end followed by an isolated DC-DC stage to comply with -48 V battery plant standards. The ICE2PCS05GXUMA1's wide VCC range and programmable switching frequency make it suitable for 1U rectifier modules up to approximately 1500 W when paired with a 600 V boost MOSFET and a high-current inductor. The integrated bulk-cap OVP is particularly important for telecom applications where the 400 V bulk rail must be tightly bounded to protect the downstream DC-DC transformer insulation. External current-sense supports accurate average-current control needed to maintain <5% THDi under parallel-module operation.
Recommended
Renewable / Solar Inverter Auxiliary SMPS
String solar inverters and battery-storage PCS require an internal auxiliary SMPS to power gate drivers, fans, and control boards, typically fed from the high-voltage DC bus. The ICE2PCS05GXUMA1 can be configured as a CCM PFC front-end for these auxiliary supplies to ensure the inverter meets conducted-emissions and harmonic limits even when the AC grid is unstable. Its BiCMOS gate driver and 250 kHz maximum frequency allow a compact boost inductor suitable for the constrained mechanical envelope of a wall-mounted inverter. The bulk-cap OVP protects the downstream auxiliary rails if the main inverter shuts down unexpectedly.

Design Notes
Place the current-sense resistor (typically 10-50 mOhm) directly in the source-return path of the external boost MOSFET, with the ISENSE pin trace kept short (under 10 mm) and routed away from the GATE driver trace to avoid capacitive coupling. According to Infineon application notes, a 100 ohm series resistor plus 1 nF to GND at the ISENSE pin forms a low-pass filter that suppresses leading-edge switching spikes without distorting the average-current signal. The VCC decoupling should use a 100 nF ceramic in parallel with at least 10 uF electrolytic placed within 5 mm of the VCC pin.
The bulk-cap OVP comparator monitors the VFB pin directly; ensure the resistor divider from the +400 V bulk rail to VFB is sized so that an output voltage of approximately 110% of nominal triggers OVP, but keep the divider impedance above 1 MOhm to minimize standby loss. Also note that VCC must rise above the UVLO turn-on threshold before the GATE pin begins switching - if the auxiliary winding is wound too low, the controller may never start at minimum line (85 VAC). Verify VCC under minimum-load and minimum-line conditions on the bench, not only at nominal 230 VAC.
Although the ICE2PCS05GXUMA1 dissipates only modest power (typical quiescent current around 10 mA at VCC=15 V gives 150 mW), the 8-pin PG-DSO package has a junction-to-ambient thermal resistance around 150 C/W. In enclosed adapters at 40 C ambient, this means a roughly 22 C junction rise above ambient - well within the 125 C limit - but verify with thermocouple measurements if the controller is co-located with heat-generating components such as the boost diode or downstream DC-DC MOSFETs.
Estimated: based on Infineon datasheet information, for a 200 W universal-input boost PFC running at 65 kHz with a 600 uH inductor, the peak inductor current is approximately 4 A at full load. The current-sense resistor should be rated for at least 2x continuous power (that is, I^2 x R with 50% margin) and have low inductance (Kelvin-connected sense footprint preferred). Use a low-ESR ceramic bypass (1 uF X7R) at the VFB pin to filter switching noise injected from the bulk-cap divider.
