Infineon Technologies ICE2PCS02XKLA1

Overview

ICE2PCS02XKLA1 from Infineon Technologies is a standalone continuous conduction mode (CCM) power factor correction (PFC) controller in PG-DIP-8 package, featuring 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 implements average current control for boost-topology PFC stages in universal-input AC-DC front-ends up to 300 W.

For engineers reviewing the ICE2PCS02XKLA1 datasheet, ICE2PCS02XKLA1 pinout, ICE2PCS02XKLA1 application, or ICE2PCS02XKLA1 equivalent, key selection criteria include its CCM-only operation with light-load DCM fallback, external voltage/current loop compensation flexibility, 95% max duty cycle at 25°C, and integrated protections including soft overcurrent, open-loop detection, and output overvoltage lockout.

Technical Context

The ICE2PCS02XKLA1 employs cascaded inner current and outer voltage loops: the current loop uses average sensing via ISENSE pin with external compensation at ICOMP, while the voltage loop regulates VOUT via resistive divider feedback to VSENSE and compensation network at VCOMP. Its nonlinear gain block shapes current reference to match sinusoidal line voltage.

Startup is controlled by VCC UVLO (11.8 V turn-on, 11 V shutdown), VINS brown-out hysteresis (0.71 V off / 1.5 V on), and VSENSE-based standby entry (<0.6 V). Gate drive delivers 1.5 A source / 2.0 A sink with 15 V clamp, enabling direct MOSFET driving without external buffers in medium-power designs.

FAQ

What is the purpose of the VINS pin on ICE2PCS02XKLA1?

The VINS pin provides direct input brown-out protection by sensing a filtered version of the rectified AC line voltage. When VINS falls below 0.71 V, the IC enters standby mode to prevent unstable operation during low-line conditions; it resumes normal operation when VINS rises above 1.5 V. This eliminates the need for an external brown-out supervisor and improves system robustness in fluctuating grid environments.

Can ICE2PCS02XKLA1 operate in discontinuous conduction mode (DCM)?

ICE2PCS02XKLA1 is designed primarily for continuous conduction mode (CCM) operation to achieve high PF and low THD. However, under light-load conditions-depending on boost inductor value and output power-it may naturally transition into DCM. This fallback behavior is intentional, maintains Class D compliance per IEC 61000-3-2, and does not require mode-switching circuitry or configuration changes.

How is the 65 kHz switching frequency trimmed and stabilized?

The 65 kHz switching frequency is trimmed during wafer test and laser-fused into the die; it is fixed internally with ±5% tolerance at 25°C and exhibits typical drift of ±10% over –40°C to +125°C junction temperature. No external components affect this frequency, ensuring consistent EMI signature and predictable filter design across production lots and operating conditions.

What protection features are integrated into ICE2PCS02XKLA1?

ICE2PCS02XKLA1 integrates six hardware-level protections: VCC under-voltage lockout (UVLO), input brown-out protection (IBOP), cycle-by-cycle peak current limiting (PCL), soft overcurrent control (SOC), open-loop protection (OLP), and output overvoltage protection (OVP). All activate autonomously without software or external circuitry, ensuring fail-safe shutdown during fault conditions such as feedback loss, short-circuit, or overvoltage events.
