Product details
Overview
ICE1PCS02FKLA1 from Infineon Technologies is an 8-pin Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller IC for boost-topology AC-DC front-ends, featuring a trimmed internal 65 kHz switching frequency (±7.7% at 25°C), 5 V ±2% internal reference, and input brown-out protection with 0.8 V turn-off / 1.5 V turn-on thresholds. It delivers 1.5 A gate drive output and supports 85–265 VAC universal input.
For engineers reviewing the ICE1PCS02FKLA1 datasheet, ICE1PCS02FKLA1 pinout, ICE1PCS02FKLA1 application, or ICE1PCS02FKLA1 equivalent, key selection criteria include average current control architecture, external voltage/current loop compensation flexibility, fast startup with controlled 30 µA VCOMP charging, soft overcurrent protection, and Class D IEC 61000-3-2 compliance in CCM operation.
Technical Context
The ICE1PCS02FKLA1 implements cascaded dual-loop control: an inner average current loop using ISENSE feedback and nonlinear gain shaping, and an outer voltage loop regulating VOUT via VSENSE with OTA1-based error amplification. Both loops use externally configured RC networks on ICOMP and VCOMP pins for full stability tuning.
Its protection architecture integrates cycle-by-cycle peak current limiting, open-loop detection, over-voltage protection (4.75–5.25 V window), VCC under-voltage lockout (11.2 V turn-on / 10.2 V shutdown), and dedicated brown-out sensing on VINS with hysteresis-enabling robust operation across wide-input AC mains with fast fault response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 65 kHz ±7.7% at 25°C - fixed internal oscillator enables predictable EMI filter design and eliminates timing component drift. |
| Internal Reference Voltage | 5 V ±2% - ensures precise 300 V–400 V DC bus regulation and tight OVP/UVLO thresholds. |
| VINS Brown-Out Threshold | Turn-off at <0.8 V, turn-on at >1.5 V - provides hysteresis to prevent chatter during marginal AC line sags. |
| GATE Drive Capability | 1.5 A source/sink, 11.5 V clamp - directly drives MOSFET gates in high-power PFC stages without external buffer. |
| VCC Operating Range | 10–21 V, UVLO at 10.2 V / 11.2 V - compatible with standard auxiliary supplies and supports standby mode at 3 mA quiescent current. |
| Startup Current Source | 30 µA (typ) into VCOMP - enables linear, stress-free VOUT ramp-up from zero load to full output. |
| Max Duty Cycle | 97% (typ) - supports high step-up ratios in universal-input boost converters with minimal conduction loss. |
Pinout & Package
ICE1PCS02FKLA1 is housed in PG-DIP-8 package (8-pin dual in-line plastic), with through-hole mounting and 0.3 inch lead spacing. Pin 1 is located at the left end of the top row when viewed from the top with notch or dot orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | IC Ground Reference | Primary return path for all internal analog and power circuits; must be connected to low-impedance system ground plane. |
| 2 ICOMP | Current Loop Compensation Node | Connects external RC network to stabilize inner current loop; integrates OTA2 output for average current regulation. |
| 3 ISENSE | Current Sense Input | Accepts voltage drop across external shunt resistor (R1); feeds both average current control and cycle-by-cycle peak limiting. |
| 4 VINS | Brown-Out Sense Input | Monitors scaled AC line voltage; triggers shutdown below 0.8 V and restart above 1.5 V with built-in hysteresis. |
| 5 VCOMP | Voltage Loop Compensation Node | Hosts external RC network for outer voltage loop stability; receives OTA1 output during startup and regulation. |
| 6 VSENSE | VOUT Feedback Input | Receives scaled DC bus voltage; compares against 5 V reference to generate error signal for voltage regulation. |
| 7 VCC | Power Supply Input | Accepts 10–21 V auxiliary supply; internal UVLO disables operation below 10.2 V and enables above 11.2 V. |
| 8 GATE | High-Current Gate Driver Output | Drives PFC switch gate with 1.5 A peak current and clamped 11.5 V output; minimizes external driver requirements. |
Key Features
| Feature | Design Value |
|---|---|
| Average Current Control Architecture | Enables sinusoidal input current draw and Class D harmonic compliance without requiring complex digital control. |
| External Loop Compensation | Full user control over both voltage (VCOMP) and current (ICOMP) loop dynamics via discrete RC networks. |
| Direct Brown-Out Sensing with Hysteresis | Eliminates need for external supervisor IC by integrating VINS threshold detection with 0.7 V hysteresis window. |
| Faster Startup with Fixed 30 µA Charging | Reduces time-to-regulation by 40% vs. ICE1PCS01; avoids inrush stress on bulk capacitor and PFC switch. |
| Soft Overcurrent Protection (SOC) | Gradually reduces duty cycle before hard shutdown-prevents nuisance tripping during transient load surges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCM PFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE1PCS01G | No brown-out protection; slower 10 µA startup current; same 65 kHz frequency and pinout. | Lacks VINS monitoring-requires external brown-out circuitry for line-sag resilience. | Select only if brown-out immunity is not required and longer startup is acceptable. |
| UCC28070 | Interleaved dual-channel CCM controller; 65–135 kHz programmable frequency; no integrated brown-out sense. | Supports higher power via interleaving but adds complexity; requires external brown-out comparator. | Choose for >500 W systems needing lower ripple and thermal distribution, accepting added BOM count. |
Compared with ICE1PCS01G and UCC28070, ICE1PCS02FKLA1 uniquely combines integrated brown-out hysteresis, fast 30 µA startup, and single-channel simplicity-making it optimal for cost-sensitive, universal-input 100–300 W PFC stages where reliability under line fluctuation is critical.

FAQ
What is the function of the VINS pin on ICE1PCS02FKLA1?
The VINS pin senses a scaled version of the AC input voltage via an external resistive divider. It triggers brown-out protection when voltage drops below 0.8 V (shutdown) and re-enables operation when voltage rises above 1.5 V, providing 0.7 V hysteresis to prevent oscillation during marginal line conditions.
Can ICE1PCS02FKLA1 operate in discontinuous conduction mode (DCM)?
ICE1PCS02FKLA1 is optimized for continuous conduction mode (CCM) operation but may enter DCM under very light loads depending on boost inductor value. Its average current control and protection features remain functional in DCM, though harmonic performance degrades slightly while still meeting IEC 61000-3-2 Class D limits.
How does the ICE1PCS02FKLA1 achieve fast startup?
It sources a constant 30 µA (typ) current into the VCOMP compensation network during startup, causing linear ramp-up of the control voltage. This results in controlled, stress-free rise of input current and output voltage-reducing time-to-regulation by ~40% compared to the ICE1PCS01G's 10 µA startup current.
Is external current-sense resistor protection required on the ISENSE pin?
Yes-a series resistor (~220 Ω) is recommended between the external sense resistor and ISENSE pin to limit inrush current during startup. Without it, high di/dt events can drive excessive current into the pin, exceeding its absolute maximum rating of ±10 mA and risking latch-up or damage.
