Infineon Technologies ICE5BR2280BZXKLA1

Overview

ICE5BR2280BZXKLA1 from Infineon Technologies is a fixed-frequency 800 V integrated power IC (CoolSET™) combining a PWM controller and avalanche-rugged CoolMOS™ in a single PG-DIP-7 package, operating at 65 kHz with 2.13 Ω R_DS(on), supporting up to 40 W in flyback and 700 mA in non-isolated buck topologies for auxiliary power supplies in home appliances and smart metering.

For engineers reviewing the ICE5BR2280BZXKLA1 datasheet, ICE5BR2280BZXKLA1 pinout, ICE5BR2280BZXKLA1 application, or ICE5BR2280BZXKLA1 equivalent, key selection considerations include its integrated error amplifier for direct feedback in non-isolated designs, selectable Active Burst Mode for ultra-low standby power, digital frequency reduction for light-load efficiency, and comprehensive auto-restart protections including VCC OVP/UVP, overload, open-loop, and overtemperature.

Technical Context

The device implements peak current-mode control with slope compensation and cycle-by-cycle current limiting, enabling stable DCM and CCM operation across 85–300 VAC input. Its cascode configuration integrates the 800 V CoolMOS™ high-side switch with the controller chip, enabling fast startup and reducing external component count.

Digital control logic manages soft start, frequency jitter, soft gate driving, and Active Burst Mode with configurable entry/exit thresholds. The built-in transconductance error amplifier (VERR pin) supports direct feedback in non-isolated flyback and buck converters without optocoupler or TL431.

FAQ

What is the function of the VERR pin?

The VERR pin is the output of the integrated transconductance error amplifier. In non-isolated buck or flyback topologies, it connects directly to the feedback network to regulate output voltage without external error amplifiers. For isolated designs, it must be tied to GND to disable the internal amplifier and allow optocoupler-based feedback via the FB pin.

Does ICE5BR2280BZXKLA1 support both DCM and CCM operation?

Yes - the device supports both discontinuous conduction mode (DCM) and continuous conduction mode (CCM) via built-in slope compensation and peak current-mode control logic. DCM is typical for low-power auxiliary supplies (<24 W), while CCM enables higher power density up to 40 W with proper transformer design and thermal management.

How is Active Burst Mode configured?

Active Burst Mode entry and exit thresholds are set externally using two resistors (R_sel and optional R_ovs3) connected to the FB pin. The datasheet provides standard resistor values for 50 mW and 100 mW standby targets. Burst mode detection is digital and fully integrated - no external timing capacitors are needed.

What protection features are included and how do they behave?

All protections - VCC overvoltage/undervoltage, overload, open-loop, overtemperature, and VCC short-to-GND - operate in auto-restart mode. After fault detection, the IC disables switching, waits a fixed timeout (~1 s), then attempts restart. Overtemperature uses junction-sensing with hysteresis (T_{jcon_OTP} = 150°C, T_{jHYS_OTP} = 20°C) to prevent thermal runaway.
