Infineon Technologies ICE3AR2280VJZXKLA1

Overview

ICE3AR2280VJZXKLA1 from Infineon Technologies is an off-line AC/DC current-mode PWM controller with integrated 800 V avalanche-rugged CoolMOS™ transistor, startup cell, input overvoltage protection (OVP), and frequency jittering - all in a PG-DIP-7 package. It delivers 43 W at 230 VAC ±15%, operates at a fixed 100 kHz switching frequency, features ±5% current-limit tolerance, and achieves <100 mW standby power via Active Burst Mode.

For engineers reviewing the ICE3AR2280VJZXKLA1 datasheet, ICE3AR2280VJZXKLA1 pinout, ICE3AR2280VJZXKLA1 application, or ICE3AR2280VJZXKLA1 equivalent, key selection criteria include input OVP configurability, 800 V drain voltage rating, DIP-7 thermal layout compatibility, Active Burst Mode entry/exit level adjustability, and built-in 10 ms soft-start timing.

Technical Context

This device integrates a BiCMOS control IC and an 800 V CoolMOS™ power transistor in one monolithic DIP-7 package, eliminating external high-voltage MOSFET and startup resistor requirements. Its control architecture includes propagation delay compensation, adjustable blanking window (20 ms base + extendable), and patented Active Burst Mode for ultra-low standby consumption.

The controller implements precise peak-current limiting (<±5% tolerance), auto-restart protection for overtemperature (50°C hysteresis), overvoltage (VCC & input), overload, and open-loop faults. Input OVP is implemented via the BV pin, enabling programmable trip threshold independent of bulk capacitor voltage scaling.

Key Specifications

Pinout & Package

Package: PG-DIP-7 (Plastic Dual In-line Package, 7-pin, wide-body, creepage-optimized for 800 V isolation). Pin 6 is omitted (no pin); pin 4 is internally not connected (n.c.). Thermal pad is absent; PCB copper area must be used for heatsinking.

Compared with ICE3AR2280JZ and ICE3BR2280JZ, the ICE3AR2280VJZXKLA1 uniquely trades brownout detection for dedicated input OVP configurability - optimizing for regions with unstable high-voltage grids while retaining full Active Burst Mode and thermal protection integrity.

FAQ

What is the purpose of the BV pin on ICE3AR2280VJZXKLA1?

The BV pin serves two simultaneous functions: it accepts a resistive voltage divider from the rectified AC line to trigger input overvoltage protection (OVP), and it extends the leading-edge blanking time during overload conditions. Its dual role eliminates the need for separate OVP and blanking circuitry, reducing external component count while maintaining precise fault response timing across operating conditions.

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

Active Burst Mode dynamically disables switching cycles when output load falls below a user-defined threshold, then resumes operation only when output voltage droop exceeds a second threshold. This controlled on/off cycling - combined with low-quiescent-current BiCMOS design and optimized gate drive - limits average input power to <100 mW at no load while maintaining tight output regulation and low ripple during active bursts.

Can ICE3AR2280VJZXKLA1 replace ICE3AR2280JZ without hardware changes?

No - although both use the same DIP-7 package and share core functionality, ICE3AR2280VJZXKLA1 replaces the brownout detection pin with input OVP capability on the BV pin. Direct replacement requires verifying that the existing resistor network on BV matches the new OVP threshold requirement and confirming that brownout protection is either unnecessary or implemented externally in the target design.

What thermal considerations apply to ICE3AR2280VJZXKLA1 in DIP-7?

The DIP-7 package lacks an exposed thermal pad; heat dissipation relies entirely on PCB copper area connected to pins 3 (CS) and 5 (Drain). Infineon recommends ≥4 cm² of 2 oz copper pour per pin, with thermal vias to inner layers. At 43 W output, junction temperature must be verified to stay ≤125°C under worst-case ambient (50°C) and airflow conditions - derating is required above 50°C ambient without forced cooling.
