Infineon ICE5AR4780BZSXKLA1, 1 Power Switch IC 7-Pin, DIP

The Infineon fixed frequency 700 V/800 V CoolSET is the 5 th generation of fixed frequency integrated power IC optimized for off-line switch mode power supply in cascode configuration. The CoolSET package has 2 separate chips inside
one is controller chip and the other is a 700 V/ 800 V CoolMOS chip. The cascode configuration helps achieve fast start-up. The frequency reduction with soft gate driving and frequency jitter operation offers lower EMI and better efficiency between light load and 50% load. The selectable entry and exit standby power ABM enables flexibility and ultra-low power consumption at standby mode with small and controllable output voltage ripple.

Enhanced Active Burst Mode with selectable entry and exit standby power
Digital frequency reduction for better overall system efficiency
Fast start-up achieved with cascode configuration
DCM and CCM operation with slope compensation
Frequency jitter and soft gate driving for low EMI
Built-in digital soft start
Integrated error amplifier to support direct feedback in non-isolated fly back
Comprehensive protection with VCC over voltage,
VCC under voltage, overload/open loop, over temperature
All protections are in auto restart mode
