Infineon Technologies ICE3AR10080CJZXKLA1

Overview

ICE3AR10080CJZXKLA1 from Infineon Technologies is an off-line AC/DC current-mode PWM controller with integrated 800V avalanche-rugged CoolMOS® power transistor and startup cell, designed for low-power SMPS in auxiliary supplies and consumer adapters. It operates at a fixed 100kHz switching frequency with jittering, delivers up to 15W output power at 230VAC ±15%, supports CCM/DCM operation with slope compensation, and includes brownout detection, active burst mode (<100mW standby), and auto-restart protection.

For engineers reviewing the ICE3AR10080CJZXKLA1 datasheet, ICE3AR10080CJZXKLA1 pinout, ICE3AR10080CJZXKLA1 application, or ICE3AR10080CJZXKLA1 equivalent, key selection considerations include its integrated 800V MOSFET voltage margin, selectable burst entry/exit thresholds, built-in 10ms soft-start and 40ms blanking time, propagation delay-compensated over-power protection, and BiCMOS-based VCC operating range (10.5–24.7V).

Technical Context

This device integrates a current-mode PWM controller, 800V CoolMOS® transistor, and startup cell in a single PG-DIP-7 package. Its control architecture features cycle-by-cycle current limiting with leading-edge blanking, precise peak-current threshold (typ. 0.45V at CS), and slope compensation for stable CCM operation above 50% duty cycle.

The power management system uses a dedicated startup cell delivering 1.0mA charge current to VCC until VCCon = 17V, then disables itself to eliminate standby loss. Protection functions include latch-enabled fast AC reset (BRL pin), brownout shutdown below 1V on BRL, overtemperature shutdown with 50°C hysteresis, and auto-restart for VCC OVP/UVP, overload, and open-loop faults.

Key Specifications

Pinout & Package

ICE3AR10080CJZXKLA1 is housed in a PG-DIP-7 package (7-pin dual in-line plastic, 10.16mm body width, 7.62mm lead pitch), with Pin 6 omitted (no connection) and Pin 4 internally unconnected (n.c.). The package supports through-hole mounting and provides creepage/clearance suitable for reinforced insulation in Class II applications.

FAQ

What is the purpose of the BRL pin and how does it differ from standard enable pins?

The BRL pin integrates three distinct functions: brownout detection (shuts down switching when voltage drops below 1.0V), fast AC reset (recovers from latch mode upon AC line restoration with controlled dV/dt), and external latch enable (forces immediate shutdown when pulled below 0.4V). Unlike simple enable pins, BRL provides coordinated, voltage-threshold-based control over multiple protection states without external logic.

How does the active burst mode achieve <100mW standby power?

Active burst mode reduces standby power by dynamically gating the PWM oscillator-only enabling switching pulses in short bursts when output voltage droop exceeds a user-defined threshold on the FBB pin. Combined with BiCMOS process technology, low-quiescent current design, and elimination of external startup resistors, this achieves sub-100mW no-load consumption while maintaining tight output regulation.

Can ICE3AR10080CJZXKLA1 operate in continuous conduction mode (CCM)?

Yes-this device explicitly supports CCM operation via integrated slope compensation, which stabilizes current-mode control when duty cycle exceeds 50%. The compensation slope is internally generated and synchronized to the oscillator, eliminating need for external ramp injection and ensuring reliable performance across line and load variations in high-efficiency flyback designs.

What is the significance of the "800V" rating in the part number?

The "800V" denotes the drain-source breakdown voltage (V_DS) of the integrated CoolMOS® transistor. This rating provides sufficient margin against voltage spikes and surges on universal AC inputs (85–265VAC), enabling robust operation without external snubbers in most auxiliary supply applications and supporting higher primary turns ratios for improved efficiency and isolation.
