Product details
Overview
ICE1CS02GXUMA1 from Infineon Technologies is a fixed-frequency continuous-conduction-mode (CCM) active power factor correction (PFC) controller IC designed for offline AC-DC converters. It operates at 65 kHz, integrates zero-current-detection (ZCD), provides overvoltage protection (OVP), and supports 8–24 V VCC operation in DSO-16 package. It is used in industrial SMPS and LED driver front-end stages.
For engineers reviewing the ICE1CS02GXUMA1 datasheet, ICE1CS02GXUMA1 pinout, ICE1CS02GXUMA1 application, or ICE1CS02GXUMA1 equivalent, key selection criteria include its integrated ZCD circuitry, fixed 65 kHz switching frequency, OVP threshold of 410 V, VCC UVLO hysteresis of 2.5 V, and DSO-16 thermal performance for high-power PFC stages.
Technical Context
This controller implements average current-mode control with internal ramp compensation to stabilize CCM operation across line and load variations. It features a dedicated ZCD input for precise inductor current zero-crossing detection and a high-voltage start-up circuit enabling direct connection to rectified AC mains.
The device includes cycle-by-cycle current limiting, adjustable output overvoltage protection via external resistor divider, and a precision reference voltage (2.5 V ±1%) for feedback regulation. Its gate driver delivers 1 A peak source/sink capability into the external MOSFET gate.

Equivalent & Alternatives
The following parts are listed as comparable options for similar active PFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2PCS01G | Variable-frequency CCM controller with soft-start and digital OVP; requires external ZCD comparator | Supports adaptive frequency sweep for improved light-load efficiency | Preferred when dynamic efficiency optimization is required over fixed-frequency EMI predictability |
| UCC28070 | Two-phase interleaved CCM controller; no integrated HV start-up; 6-pin SOIC package | Targets higher-power systems (>750 W) needing lower ripple and thermal distribution | Chosen for multi-kW telecom rectifiers where phase interleaving reduces input/output capacitor stress |
Compared with ICE2PCS01G and UCC28070, ICE1CS02GXUMA1 offers simpler board layout due to integrated ZCD and HV start-up, fixed 65 kHz operation for repeatable EMI filtering, and DSO-16 thermal performance suitable for compact 500 W designs without forced air cooling.

FAQ
What is the purpose of the RTN pin on ICE1CS02GXUMA1?
The RTN (Return) pin provides a dedicated Kelvin return path for the current-sense signal, separating it from the main power ground to eliminate PCB trace resistance errors. This improves accuracy of cycle-by-cycle current limiting, especially critical during overload and short-circuit conditions. It must be routed directly to the shunt resistor's low-side terminal.
Does ICE1CS02GXUMA1 support discontinuous conduction mode (DCM)?
No, ICE1CS02GXUMA1 is designed exclusively for continuous conduction mode (CCM) operation. It lacks DCM-specific control logic such as variable frequency modulation or valley-switching detection. Its internal ramp compensation and fixed 65 kHz oscillator are optimized for stable CCM behavior across full load and line ranges.
How is overvoltage protection (OVP) configured on this IC?
OVP is configured using an external resistor divider from the boost output to the OVP pin (pin 12), with threshold set at 410 V typical. The internal comparator triggers latch-off when the divided voltage exceeds 2.5 V. Recovery requires power cycle or VCC reset-no auto-restart function is implemented.
Can ICE1CS02GXUMA1 drive a 600 V MOSFET directly?
Yes-the OUT pin delivers ±1 A peak gate drive current and is rated for 18 V max output swing, sufficient to fully enhance common 600 V superjunction MOSFETs (e.g., IPW60R041P7) within their recommended gate charge (Qg) range. Layout must minimize gate loop inductance to avoid ringing.
