Infineon Technologies ICE2PCS02HKLA1

Overview

ICE2PCS02HKLA1 from Infineon Technologies is a standalone continuous conduction mode (CCM) power factor correction (PFC) controller in PG-DIP-8 package, featuring average current control, 65 kHz fixed switching frequency (±5% at 25°C), 3 V trimmed internal reference voltage (±2%), and direct input brown-out detection with 0.71 V shutdown / 1.5 V turn-on thresholds. It drives boost-topology PFC stages in universal-input AC-DC front-ends up to Class D IEC 61000-3-2 compliance.

For engineers reviewing the ICE2PCS02HKLA1 datasheet, ICE2PCS02HKLA1 pinout, ICE2PCS02HKLA1 application, or ICE2PCS02HKLA1 equivalent, key selection considerations include its CCM-only operation (with light-load DCM fallback), external voltage/current loop compensation, gate drive capability (1.5 A source / 2.0 A sink), soft-start behavior, and brown-out hysteresis for stable line-voltage monitoring in industrial and consumer SMPS designs.

Technical Context

The ICE2PCS02HKLA1 implements cascaded dual-loop control: an inner average current loop using ISENSE input and ICOMP compensation, and an outer voltage loop using VSENSE feedback and VCOMP network. Its nonlinear gain block shapes current reference to match sinusoidal line voltage, enabling high PF (>0.99) across 85–265 VAC input range.

Protection logic integrates cycle-by-cycle peak current limiting, soft overcurrent control, open-loop detection, output overvoltage protection, and VCC UVLO (11.8 V turn-on / 11.0 V shutdown). Startup is controlled via VCOMP ramping under OTA1 sourcing (max 30 µA), with automatic transition to steady-state regulation once VSENSE exceeds 0.6 V and VINS > 1.5 V.

Key Specifications

Pinout & Package

ICE2PCS02HKLA1 is housed in PG-DIP-8 (Plastic Dual In-line Package, 8-pin), a through-hole package with 2.54 mm pitch, suitable for industrial-grade PCB assembly and thermal management in offline PFC applications.

FAQ

What is the maximum recommended output power for ICE2PCS02HKLA1 in continuous conduction mode?

The ICE2PCS02HKLA1 is validated for reliable operation up to 300 W in boost topology with standard 600 V MOSFETs and typical EMI filter/choke designs. At this level, thermal performance remains within safe limits using PG-DIP-8's inherent thermal resistance (R_thJA ≈ 65°C/W), and gate drive capability sustains required peak currents without external buffering.

Does ICE2PCS02HKLA1 support discontinuous conduction mode (DCM) operation?

No - ICE2PCS02HKLA1 is designed exclusively for continuous conduction mode (CCM) control. Under very light loads, the system may naturally enter DCM due to inductor current decay, but the IC does not regulate or optimize for DCM; its average current control loop assumes CCM operation for accurate sinusoidal shaping and Class D compliance.

How is the 65 kHz switching frequency trimmed and stabilized?

The 65 kHz oscillator frequency is factory-trimmed using laser or fuse-based calibration during final test, achieving ±5% tolerance at 25°C. No external components affect frequency; temperature drift is specified as ±0.3%/°C over –25°C to +125°C ambient, ensuring stable timing across industrial operating ranges without compensation networks.

Can ICE2PCS02HKLA1 be used with a 12 V auxiliary supply?

Yes - the VCC pin operates from 11 V to 25 V, making a regulated 12 V auxiliary supply fully compatible. However, ensure the supply can deliver ≥10 mA during normal operation and withstand brief inrush transients; also verify that VCC remains above 11.0 V under worst-case line dips to avoid unintended UVLO shutdown.
