Infineon Technologies ICE3AR1080VJZXKLA1

Overview

ICE3AR1080VJZXKLA1 from Infineon Technologies is an off-line SMPS current-mode controller IC integrating an 800 V avalanche-rugged CoolMOS™ transistor, startup cell, input overvoltage protection (OVP), and frequency jittering - all in a PG-DIP-7 package. It operates at a fixed 100 kHz switching frequency, delivers up to 71 W at 230 VAC ±15%, supports active burst mode for <100 mW standby power, and features precise ±5% current limiting tolerance. It is designed for universal-input AC/DC adapters and auxiliary power supplies in consumer electronics.

For engineers reviewing the ICE3AR1080VJZXKLA1 datasheet, ICE3AR1080VJZXKLA1 pinout, ICE3AR1080VJZXKLA1 application, or ICE3AR1080VJZXKLA1 equivalent, key selection considerations include its integrated 800 V CoolMOS™, input OVP capability via BV pin, 10 ms built-in soft-start, 20 ms extendable blanking time, and active burst mode with selectable entry/exit thresholds - all critical for low-EMI, high-efficiency, and safety-compliant offline flyback designs.

Technical Context

This device implements a current-mode PWM control architecture with patented propagation delay compensation and dual-blanking modes (basic + extendable) to maintain stable peak-current regulation under transient load jumps and burst-mode transitions. The control unit integrates auto-restart protection for overtemperature (50°C hysteresis), VCC over/under-voltage, open-loop, and overload conditions.

The integrated CoolMOS™ section enables direct high-voltage drain connection (800 V rating), eliminating external HV startup resistors and reducing component count. The BV pin serves a dual role: setting input OVP threshold and extending blanking window duration - enabling robust line-sensing and high-dV/dt immunity without external circuitry.

FAQ

What is the purpose of the BV pin on ICE3AR1080VJZXKLA1?

The BV pin serves two confirmed functions: (1) input overvoltage protection - triggering shutdown when the resistor-divider voltage exceeds ~1.25 V, corresponding to line voltages above user-defined thresholds (e.g., 310 VDC); and (2) extending the blanking window duration during overload events to prevent false current-limit trips. Its dual role eliminates need for external OVP comparators and blanking timers.

Does ICE3AR1080VJZXKLA1 require an external startup resistor?

No. ICE3AR1080VJZXKLA1 integrates a dedicated startup cell within the CoolMOS™ structure, enabling direct connection of the Drain pin to the rectified mains. This eliminates the external high-voltage startup resistor typically required in discrete controller + MOSFET solutions, reducing component count, power loss, and PCB footprint.

How does Active Burst Mode reduce standby power below 100 mW?

Active Burst Mode dynamically reduces switching frequency under light load while maintaining closed-loop regulation via the FBB pin. During burst cycles, the controller enters extended sleep periods between short high-frequency bursts, minimizing gate drive losses and transformer core losses. Combined with BiCMOS low-quiescent design and soft gate drive, this achieves measured standby power of 78 mW at 230 VAC input.

Can ICE3AR1080VJZXKLA1 be used in quasi-resonant (QR) flyback topologies?

No. ICE3AR1080VJZXKLA1 is a fixed-frequency (100 kHz) current-mode controller with jittering, not a valley-switching QR controller. It lacks zero-current detection circuitry and variable-frequency control logic required for QR operation. It is optimized for continuous and discontinuous conduction mode (CCM/DCM) flyback designs with predictable timing and robust overload handling.
