Infineon Technologies ICE2A180ZXKLA1

Overview

ICE2A180ZXKLA1 from Infineon Technologies is an off-line AC/DC current-mode PWM controller with integrated 800V CoolMOS™ power transistor in PG-DIP-7-1 package, delivering 29W output power at 230VAC ±15%, operating at 100kHz switching frequency with 3.0Ω R_DS(on), and featuring auto-restart protection, frequency reduction for low standby power, and ±5% peak current limiting tolerance.

For engineers reviewing the ICE2A180ZXKLA1 datasheet, ICE2A180ZXKLA1 pinout, ICE2A180ZXKLA1 application, or ICE2A180ZXKLA1 equivalent, key selection considerations include its 800V drain rating for universal input designs, DIP-7 footprint compatibility with board-level creepage requirements, precise current sensing via Isense pin, and thermal shutdown behavior during overload conditions.

Technical Context

The ICE2A180ZXKLA1 integrates a current-mode PWM controller and an 800V avalanche-rugged CoolMOS™ transistor in a single PG-DIP-7-1 package, eliminating external high-voltage MOSFET layout complexity. Its control architecture includes internal leading-edge blanking, propagation delay compensation, and a dedicated SoftS pin that manages both startup soft-start and auto-restart sequencing after fault detection.

It operates across 85–265VAC input with VCC supply range 8.5–21V, features 72% max duty cycle, and implements frequency reduction to 20–21.5kHz in standby mode to meet European Commission low-power requirements while avoiding audible noise. Protection functions include overvoltage, open-loop, overload, and thermal shutdown - all routed through a unified internal protection unit triggering auto-restart.

Key Specifications

Pinout & Package

ICE2A180ZXKLA1 uses the PG-DIP-7-1 package - a 7-pin dual-in-line plastic package with increased creepage distance for primary-side isolation compliance. Pin 6 is not connected (N.C.), and Drain pins (5) are internally tied to the CoolMOS™ drain terminal.

FAQ

What is the maximum continuous output power of ICE2A180ZXKLA1 at 115VAC input?

At 115VAC ±15%, ICE2A180ZXKLA1 delivers up to 22W continuous output power under standard test conditions (T_a=75°C, T_j=125°C, 6cm² copper area). This reflects derating from its 29W rating at 230VAC due to higher RMS current and conduction losses at lower input voltage.

Can ICE2A180ZXKLA1 be used in non-isolated buck-derived topologies?

No - ICE2A180ZXKLA1 is designed exclusively for isolated flyback and forward converter topologies. Its Drain pin is referenced to primary ground and lacks level-shifting capability for high-side buck switch control; the FB and Isense architecture assumes optocoupler-based secondary regulation.

How does the SoftS pin function during overvoltage fault recovery?

During overvoltage fault, the internal protection unit forces auto-restart mode: the SoftS pin discharges its external capacitor, then recharges linearly to initiate soft-start again after a fixed delay. This sequence repeats until fault condition clears, preventing uncontrolled power delivery.

Is external R_DS(on) temperature compensation required for peak current accuracy?

No - ICE2A180ZXKLA1 includes internal propagation delay compensation and temperature-stable current-sense threshold circuitry. The ±5% total peak current limit tolerance includes drift across -25°C to +125°C junction temperature, eliminating need for external compensation networks.
