Product details
Overview
ICE2PCS03HKLA1 from Infineon Technologies is a standalone Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller IC for boost-topology AC-DC front-ends. It features a trimmed internal 100 kHz switching frequency (±5% at 25°C), 3 V ±2% internal reference voltage, and direct input brown-out detection with hysteresis (turn-on at VINS > 1.5 V, shutdown at VINS < 0.71 V). Designed for universal-input (85–265 VAC) industrial and consumer SMPS requiring Class D IEC 61000-3-2 compliance.
For engineers reviewing the ICE2PCS03HKLA1 datasheet, ICE2PCS03HKLA1 pinout, ICE2PCS03HKLA1 application, or ICE2PCS03HKLA1 equivalent, this controller delivers average-current-mode control with external voltage/current loop compensation, fast dynamic response to load jumps, soft-start with linear VCOMP ramping, and integrated protections including OVP, OLP, SOC, PCL, and UVLO on VCC (11.8 V turn-on, 11 V shutdown).
Technical Context
The ICE2PCS03HKLA1 implements cascaded dual-loop control: an inner average current loop shaped by ISENSE and ICOMP, and an outer voltage loop regulated via VSENSE and VCOMP. Its nonlinear gain block enables sinusoidal input current tracking across the full AC line cycle without multiplier circuitry.
It operates exclusively in CCM under normal load but transitions to DCM only at light loads-still meeting IEC 61000-3-2 Class D harmonic limits. The fixed 100 kHz oscillator eliminates external timing components, while the GATE driver delivers 1.5 A source / 2.0 A sink capability with 15 V clamp, directly driving MOSFET gates in high-efficiency PFC stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 100 kHz ±5% at 25°C - eliminates need for external timing resistor/capacitor; ensures stable EMI profile. |
| Internal Reference Voltage | 3.0 V ±2% - sets precise output bus regulation threshold at VSENSE; enables accurate 380–400 V DC bus control. |
| VCC Operating Range | 11 V to 26 V - supports auxiliary supply designs with wide tolerance; UVLO activates at 11.0 V (off) / 11.8 V (on). |
| Brown-Out Threshold | VINS < 0.71 V (shutdown), > 1.5 V (restart) - prevents unstable operation during low-line sags without false triggering. |
| GATE Drive Capability | 1.5 A source / 2.0 A sink, 15 V clamped - directly drives medium-power CoolMOS™/Superjunction MOSFETs without external buffer. |
| Max Duty Cycle | 95% typical - enables high step-up ratio in boost converters with low input voltage (e.g., 85 VAC → 380 VDC). |
| Protection Features | OVP, OLP, SOC, PCL, IBOP, UVLO - autonomous fault handling without microcontroller intervention; reduces BOM count. |
Pinout & Package
ICE2PCS03HKLA1 is housed in PG-DIP-8 (Plastic Dual-In-Line Package, 8-pin, 0.3 inch width), RoHS-compliant and lead-free. Pin spacing is 2.54 mm, body width 9.27 mm, height 4.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | IC Ground Reference | Primary return path for all analog and power circuits; must be low-inductance connection to system power 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 via resistive divider; triggers shutdown below 0.71 V to prevent unstable boost operation. |
| 5 VCOMP | Voltage Loop Compensation Node | Output of outer voltage loop OTA1; connects external RC network to set bandwidth and phase margin for bus regulation. |
| 6 VSENSE | VOUT Feedback Input | Receives scaled output bus voltage; compares against 3 V internal reference to regulate 380–400 V DC output. |
| 7 VCC | IC Supply Input | Accepts 11–26 V auxiliary supply; internal UVLO ensures clean startup and safe shutdown during supply faults. |
| 8 GATE | MOSFET Gate Driver Output | Drives boost switch gate directly; 15 V clamp protects MOSFET gate oxide; high sink current enables fast turn-off. |
Key Features
| Feature | Design Value |
|---|---|
| Average Current Control Architecture | Enables sinusoidal input current without analog multiplier; meets IEC 61000-3-2 Class D with minimal external parts. |
| External Loop Compensation | Independent tuning of voltage (VCOMP) and current (ICOMP) loops allows optimization for specific choke, MOSFET, and load dynamics. |
| Fast Dynamic Load Response | Enhanced transient recovery during load jumps due to dedicated ramp generator and nonlinear gain block-no output droop beyond spec. |
| Soft-Start with Linear VCOMP Ramp | OTA1 sources up to 30 mA into VCOMP during startup, ensuring controlled rise of input current and reduced stress on bulk capacitor and diode bridge. |
| Integrated Brown-Out Protection with Hysteresis | Prevents erratic operation during brown-outs by enforcing clean restart window (0.71 V → 1.5 V), avoiding oscillation near threshold. |
Applications
| Industrial AC-DC Power Supplies | LED Driver Front-Ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCM PFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2PCS03G | Same die, PG-DSO-8 package (surface-mount); identical electrical specs and pinout mapping. | Requires reflow-compatible PCB layout; better thermal performance in dense layouts but less serviceable than DIP. | Select ICE2PCS03G for automated SMT production; ICE2PCS03HKLA1 preferred for through-hole prototyping or field-replaceable modules. |
| UCC28070 | Interleaved dual-channel CCM controller; 65–300 kHz programmable frequency; no integrated brown-out sense-requires external comparator. | Targets higher-power (>1 kW) systems needing interleaving; lacks direct VINS brown-out input and fixed 100 kHz simplicity. | Choose UCC28070 only when interleaving or variable-frequency operation is required; ICE2PCS03HKLA1 offers lower component count for single-phase ≤1 kW. |
Compared with ICE2PCS03G, ICE2PCS03HKLA1 offers identical functionality in through-hole form for manual assembly and thermal testing; versus UCC28070, it trades programmability and channel count for reduced BOM, simpler layout, and built-in brown-out protection-ideal for cost- and space-constrained single-phase PFC.

FAQ
What is the recommended external sense resistor value for ISENSE on ICE2PCS03HKLA1?
The ISENSE pin accepts voltage drops from 0 to 1.2 V. For a typical 500 W boost stage with 10 A peak inductor current, a 0.02 Ω shunt yields 200 mV at 10 A-well within range and minimizing power loss. A series 220 Ω resistor (R2) is mandatory between shunt and ISENSE to limit inrush current during startup, per Infineon's design guidelines.
Does ICE2PCS03HKLA1 support discontinuous conduction mode (DCM)?
No-the ICE2PCS03HKLA1 is designed exclusively for continuous conduction mode (CCM) operation. Under very light loads, the system may naturally enter DCM due to inductor current decay, but the IC does not control or optimize for DCM. Its average-current-loop architecture and 100 kHz fixed frequency assume CCM as the primary operating mode.
Can VCOMP and ICOMP be left unconnected if compensation is not required?
No-both VCOMP and ICOMP require external RC networks for stability. Leaving them open causes uncontrolled loop behavior, oscillation, or failure to regulate. Minimum recommended networks are 1 nF capacitor to ground on ICOMP and 10 nF + 10 kΩ series RC on VCOMP, per Figure 2 in the datasheet.
Is ICE2PCS03HKLA1 qualified for use in medical equipment?
ICE2PCS03HKLA1 is not certified for life-support applications. Infineon explicitly states that its components may be used in life-support devices only with express written approval. This part lacks ISO 13485 process certification, medical-grade reliability screening, or safety isolation-intended for industrial/consumer power supplies only.
