Infineon Technologies ICE3AR2280JGXUMA1

Overview

ICE3AR2280JGXUMA1 from Infineon is an integrated 800 V CoolMOS™ PWM controller in PG-DSO-12 package, combining avalanche-rugged high-voltage MOSFET and current-mode control logic for offline SMPS. It delivers fixed 100 kHz switching with frequency jittering, active burst mode (<100 mW standby), adjustable brownout, and auto-restart protection for overtemperature (50°C hysteresis), overload, and VCC faults - deployed in Blu-ray players, set-top boxes, and auxiliary power supplies for servers and white goods.

For engineers reviewing the ICE3AR2280JGXUMA1 datasheet, ICE3AR2280JGXUMA1 pinout, ICE3AR2280JGXUMA1 application, or ICE3AR2280JGXUMA1 equivalent, key selection criteria include its 800 V drain rating, ±5% current limit tolerance, 10 ms soft-start, 20 ms extendable blanking time, and dual-function BBA/FBB pins enabling brownout, burst-level selection, and external auto-restart enable.

Technical Context

This IC implements current-mode PWM control with propagation-delay compensation to maintain consistent peak-power limiting across input line variations. Its BiCMOS process enables wide VCC range (10.5–25 V) and low quiescent consumption, while the integrated startup cell eliminates external high-voltage start-up circuitry.

The control unit integrates patented Active Burst Mode with selectable entry/exit thresholds and feedback voltage swing reduction (0.5 V → 0.3 V) to cut output ripple by 40% during light-load operation. Brownout detection, soft gate drive (50 Ω turn-on resistor), and jittered oscillator collectively reduce EMI without external filters.

FAQ

What is the purpose of the BBA pin?

The BBA pin integrates three critical functions: brownout detection (shuts down switching below user-defined AC input), extendable blanking time (adds external capacitor to lengthen 20 ms overload blanking), and external auto-restart enable (pulling BBA <0.4 V forces immediate restart cycle). All share one pin to minimize external components while maintaining independent configurability via resistor/capacitor networks.

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

Active Burst Mode dynamically pauses switching cycles during light load instead of reducing duty cycle. The FBB pin's feedback signal determines burst entry/exit thresholds, and internal logic reduces feedback voltage swing from 0.5 V to 0.3 V during bursts - cutting output ripple by 40% and eliminating need for post-regulation LDOs, directly enabling sub-100 mW consumption without compromising regulation stability.

Can ICE3AR2280JGXUMA1 replace ICE3BR2265JGXUMA1 in existing designs?

Yes, it is pin-compatible and functionally supersets the 650 V ICE3BR2265JGXUMA1, but requires validation of primary-side snubber and transformer insulation for 800 V operation. The added brownout, extended blanking, and propagation-delay compensation improve reliability in universal-input applications - however, VCC startup timing and BBA/FBB resistor values may need adjustment to leverage new features.

What thermal protection behavior occurs above 130°C junction temperature?

At T_j >130°C, the IC triggers thermal shutdown and enters auto-restart mode with 50°C hysteresis - meaning it remains off until junction temperature falls below 80°C before attempting restart. This prevents thermal runaway during sustained overload or poor heatsinking, and the hysteresis avoids rapid cycling near trip threshold, ensuring safe recovery without manual intervention.
