Infineon Technologies ICE3RBR0665JZXKLA1

Overview

ICE3RBR0665JZXKLA1 from Infineon Technologies is an off-line AC/DC current-mode PWM controller IC with integrated 650V CoolMOS® power transistor and startup cell in PG-DIP-7 package, operating at fixed 65 kHz switching frequency, delivering up to 71W at 230VAC with <50 mW standby power in Active Burst Mode, used in universal-input auxiliary power supplies for TVs, set-top boxes, and printers.

For engineers reviewing the ICE3RBR0665JZXKLA1 datasheet, ICE3RBR0665JZXKLA1 pinout, ICE3RBR0665JZXKLA1 application, or ICE3RBR0665JZXKLA1 equivalent, key selection criteria include integrated high-voltage MOSFET ruggedness (650V), precise ±5% current limiting tolerance, external auto-restart enable via BA pin, built-in frequency jitter for EMI reduction, and extended blanking time configurability for overload robustness.

Technical Context

This controller implements a BiCMOS-based current-mode architecture with propagation delay compensation and leading-edge blanking to ensure stable peak-current regulation across line and load variations. Its integrated startup cell eliminates the need for external high-voltage resistors, reducing no-load losses and improving light-load efficiency.

The device supports two blanking modes - fixed 20 ms and extendable via external capacitor on BA pin - enabling adaptive response to transient overloads. Active Burst Mode maintains tight output regulation while minimizing switching activity during no-load conditions, achieving sub-50 mW standby consumption without compromising restart reliability.

FAQ

What is the purpose of the BA pin on ICE3RBR0665JZXKLA1?

The BA pin serves dual functions: it extends the internal 20 ms blanking window via an external capacitor to handle high-current transients, and acts as an external auto-restart enable input - pulling it below 0.33 V forces immediate gate shutdown and entry into auto-restart mode. This dual role allows designers to tailor protection behavior without adding discrete logic.

Does ICE3RBR0665JZXKLA1 require an external startup resistor?

No. The device integrates a high-voltage startup cell connected directly to the Drain pin, eliminating the need for an external high-voltage resistor. This reduces no-load power consumption, improves light-load efficiency, and simplifies the primary-side bill of materials - a key differentiator from legacy controllers like ICE3BRxx65JZ.

How does Active Burst Mode maintain output regulation at zero load?

Unlike conventional burst modes that disable feedback, ICE3RBR0665JZXKLA1 retains full optocoupler-coupled feedback via the FB pin even in Active Burst Mode. The internal control unit samples FB voltage between bursts and adjusts burst frequency and pulse width to hold output voltage within ±3%, ensuring stable regulation without secondary-side LDOs or additional compensation.

What is the maximum continuous output power achievable with this IC?

At 230 VAC ±15% input and 50°C ambient temperature with no heatsink copper area, ICE3RBR0665JZXKLA1 delivers up to 71 W in continuous conduction mode. Derating applies at lower input voltages (47 W at 85–132 VAC) and higher temperatures; actual power depends on transformer design, cooling, and safety margin requirements per IEC 62368-1.
