Typical Applications
ICE3PCS03GXUMA1 is suitable for 6 applications: Desktop PC SMPS (80 PLUS), Flat-Panel TV Power Supply, Industrial SMPS (100 W to 1 kW), LED Lighting Driver Front-End, Server & Telecom Rectifier, White Goods Inverter Power Board.
Desktop PC SMPS (80 PLUS)
The ICE3PCS03GXUMA1 is well-suited for 80 PLUS-compliant desktop PC switch-mode power supplies in the 300 W to 800 W range. Its CCM operation with adjustable switching up to 250 kHz enables power factor correction above 0.95 at full load from universal mains input, while the integrated digital control loop eliminates the external compensation network required by older analog PFC ICs. The 2.5 V trimmed reference tightens output-rail accuracy and the 0.2 V current-sense threshold minimizes sense-resistor dissipation, critical for meeting 80 PLUS Gold efficiency targets.
Recommended
Flat-Panel TV Power Supply
LCD and OLED TV power supplies typically require a PFC front-end feeding a 400 V bus for the backlight inverter and downstream DC-DC converters. The ICE3PCS03GXUMA1's wide 85-265 VAC input range and SOIC-8 footprint make it ideal for slim TV chassis where board area is constrained. The integrated protection suite, including output overvoltage, undervoltage, and open-loop detection, simplifies TV safety certification while reducing BOM cost. Light-load efficiency is also improved versus the second-generation ICE2PCS0x parts.
Recommended
Industrial SMPS (100 W to 1 kW)
Industrial power supplies require robust PFC stages with wide input range and comprehensive fault protection. The ICE3PCS03GXUMA1 delivers CCM PFC for 100 W to 1 kW industrial SMPS used in factory automation, PLCs, and motor drives. The external synchronization feature allows coordinated switching with downstream DC-DC stages, simplifying EMI filter design. The SOIC-8 package and low external component count also reduce assembly cost for high-volume industrial deployments.
Recommended
LED Lighting Driver Front-End
High-power LED drivers for street lighting, commercial luminaires, and horticultural fixtures require active PFC to meet regulatory harmonic standards such as EN 61000-3-2. The ICE3PCS03GXUMA1 supports these applications with its 85-265 VAC universal input and 0.95+ power factor capability. The integrated digital control loop maintains stable operation across the LED driver's wide load range, while the SOIC-8 footprint allows compact driver enclosures.
Recommended
Server & Telecom Rectifier
Telecom rectifier and server PSU front-ends operate from -48 V battery plants or universal AC mains, requiring high-efficiency PFC stages above 1 kW. The ICE3PCS03GXUMA1's CCM topology and 250 kHz switching capability support interleaved or single-stage PFC designs for these high-power-density applications. The external frequency synchronization feature enables multi-phase interleaving to spread thermal load and reduce input ripple.
Recommended
White Goods Inverter Power Board
Variable-frequency drives for washing machines, refrigerators, and dishwashers include a PFC front-end feeding the motor inverter. The ICE3PCS03GXUMA1 in SOIC-8 is well-suited for these cost-sensitive, space-constrained white-goods applications. Its wide input range, integrated protection, and low external component count enable compliance with IEC 61000-3-2 harmonic standards while keeping BOM cost and PCB area minimal.

Key Differentiators
- Third-generation Infineon CCM PFC controller with integrated digital control loop (vs ICE2PCS02G)
- External frequency synchronization up to 250 kHz (vs NCP1654BD65R2G (onsemi))
- Universal 85-265 VAC input range with single design (vs L6562AN (STMicroelectronics, transition-mode))
Design Notes
Place the current-sense resistor (R_sense) between the boost MOSFET source and ground using a short, wide Kelvin-sense trace to the ISENSE pin. Keep the high-current loop area (rectifier bridge, boost inductor, boost MOSFET, sense resistor) minimal to reduce EMI. The ISENSE trace should be referenced to the analog ground plane and routed away from the GATE driver trace to avoid switching-noise injection that can false-trigger the 0.2 V current limit.
Estimated VCC supply decoupling: place a 100 nF ceramic bypass capacitor as close as possible to the VCC pin (pin 5), with a 10 uF electrolytic or tantalum bulk capacitor on the same node. The VCC rail must be derived from an auxiliary winding on the boost inductor or from an external trickle-charge circuit; undervoltage lockout at the VCC threshold prevents the IC from operating below its minimum supply, which would cause undefined GATE output behavior.
Do not exceed the 0.2 V peak current-limit threshold during transient loads; overshoots above this level will trip protection and cause audible PFC output ripple. For designs above 1 kW, consider interleaving two ICE3PCS03GXUMA1 ICs 180 degrees out of phase using the SYNC pin to reduce input current ripple and shrink the EMI filter. The output overvoltage threshold should be verified against your downstream DC-DC stage's maximum input rating.
Keep the GATE drive trace (pin 6) to the boost MOSFET gate short (under 25 mm preferred) and use a 10 ohm gate resistor to damp ringing. Route the VSENSE divider (pin 1) traces away from the boost inductor to avoid switching-noise coupling. Use a guard ring or via fence around the VSENSE and COMP traces if they must cross noisy regions, and ensure the analog ground and power ground meet at a single point near the sense resistor.
