Product details

Overview

ICE5AR0680BZSXKLA1 from Infineon 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. It delivers up to 66 W output at 220 V AC in DCM, operates at 100 kHz, features 0.71 Ω R_DS(on), and supports non-isolated flyback topologies with integrated error amplifier for direct feedback.

For engineers reviewing the ICE5AR0680BZSXKLA1 datasheet, ICE5AR0680BZSXKLA1 pinout, ICE5AR0680BZSXKLA1 application, or ICE5AR0680BZSXKLA1 equivalent, key selection criteria include standby power <100 mW via selectable Active Burst Mode, digital frequency reduction for light-load efficiency, cascode-based fast startup, and comprehensive auto-restart protections including VCC OVP/UVP, overload, and OTP.

Technical Context

The device implements peak current-mode control with slope compensation for stable DCM/CCM operation across 85–300 V AC input. Its digital control unit enables frequency jittering and soft gate driving to reduce EMI, while the cascode configuration-integrating high-voltage CoolMOS™ and low-voltage controller-enables rapid VCC pre-charging and startup within milliseconds.

Active Burst Mode (ABM) is digitally configurable via FB pin biasing to set entry/exit standby power thresholds, achieving ultra-low standby consumption (<100 mW) with controlled output ripple. Protection functions-including cycle-by-cycle current limiting, leading-edge blanking, and thermal shutdown with hysteresis-are fully integrated and operate in auto-restart mode without external latching.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fixed-frequency flyback controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE5QR0680AZXKLA1	Quasi-resonant (QR) topology; no fixed 100 kHz clock; higher light-load efficiency but increased EMI complexity	Preferred for designs requiring <75 mW standby and tighter average efficiency across full load range	Choose only if QR control simplifies transformer design and EMI filtering budget allows variable-frequency operation
LD7575PG	Discrete controller + external 800 V MOSFET; no integrated error amp; requires optocoupler for all configurations	Suitable when board space permits separate components and design requires field-serviceable MOSFET replacement	Select when long-term component availability or failure-mode analysis favors modular architecture over monolithic integration

Compared with ICE5QR0680AZXKLA1, this part offers deterministic EMI behavior and simpler loop compensation; versus LD7575PG, it reduces component count and improves startup reliability but limits post-production MOSFET substitution.

FAQ

What is the maximum continuous output power supported by ICE5AR0680BZSXKLA1?

The device supports up to 66 W at 220 V AC ±20% in DCM open-frame configuration (Ta = 50 °C, TJ = 125 °C, 2 oz copper PCB). Actual output depends on transformer design, heatsinking, and ambient conditions. For CCM operation across 85–300 V AC, rated output is 41 W. Derating is required above 50 °C ambient or with reduced copper area.

How does the selectable Active Burst Mode function without external components?

ABM entry and exit thresholds are set by resistor dividers on the FB pin, which bias internal comparators to detect output load level. No external timer or logic is needed-the controller digitally samples FB voltage and transitions autonomously between PWM and burst modes while maintaining regulated output and <100 mW standby consumption.

Can ICE5AR0680BZSXKLA1 be used in non-isolated flyback topologies?

Yes-it integrates a transconductance error amplifier referenced to VERR, allowing direct feedback from secondary-side resistive divider without optocoupler or TL431. In this configuration, VERR is left floating or connected to regulation node, and FB serves as sole feedback input. This reduces component count and improves transient response in low-voltage auxiliary rails.

What protection mechanisms activate during VCC short-to-GND fault?

When VCC shorts to GND, the internal charge pump and gate driver disable immediately. The controller enters auto-restart mode after detecting VCC drop below 10.0 V UVLO threshold. During restart, GATE remains off until VCC recovers above 10.0 V and soft-start completes, preventing uncontrolled CoolMOS™ conduction and ensuring safe recovery without latch-up.
