Infineon ICE5AR4770AGXUMA1, Power Conversion 133 kHz 12-Pin, PG-DSO-12

The Infineon Switching Controller is a is the 5th generation of fixed frequency integrated power IC optimized for off line switch mode power supply in cascade configuration. The CoolSET™ package has 2 separate chips inside one is controller chip and the other is a700 V, 800 V CoolMOS™ chip. The cascade 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 percent load.
