The R2A11302FT#V9 is a power management IC designed for small AC-DC power supplies. It features an integrated high-voltage MOSFET and supports boundary conduction mode (BCM) control. The device operates with a wide input voltage range, typically from 85 VAC to 265 VAC. Key electrical parameters include a switching frequency up to 65 kHz and a supply voltage range of 14 V to 18 V. It includes built-in protections such as overvoltage, overcurrent, and thermal shutdown. The component is housed in a DIP-7 package suitable for through-hole mounting.
