ICE5AR4770AGXUMA1 AC-DC converter and offline switcher 100kHz PG-DSO-12-21
The ICE5AR4770AGXUMA1 is a high-performance fixed-frequency flyback AC-DC converter and offline switcher developed by Infineon Technologies, belonging to the advanced CoolSET™ product family, housed in a 12-pin BSOP surface-mount package with an exposed thermal pad to deliver efficient heat dissipation for continuous medium-power operation in cost-effective power supply designs.
This chip integrates a 700V avalanche-rated power MOSFET, supports a 10V to 25.5V Vcc supply voltage range, operates at a fixed 100kHz switching frequency, and delivers a maximum 25W output power with a 75% maximum duty cycle, featuring built-in enable control, soft start function and synchronization interface to simplify external circuit design and reduce overall BOM count. It integrates comprehensive fault protection mechanisms including cycle-by-cycle current limiting, open-loop detection, overload protection, over-temperature shutdown and over-voltage protection, and supports non-isolated output topologies, covering a full industrial-grade operating temperature range from -40°C to +150°C at the junction temperature. This component is fully RoHS compliant, widely deployed in consumer electronics chargers, LED driver power supplies, industrial automation auxiliary power modules and home appliance control boards, delivering high efficiency and long-term reliability for low-to-medium power offline power conversion applications.
