B0503S DC-DC Isolated Power Supply Module - 1W, 5V to 3.3V Previous 
B0509S DC-DC Isolated Power Supply Module is a 1W isolated converter designed to change a 5V DC input to a 9V DC output. It provides electrical isolation between input and output for board-level power systems. The module is intended for applications that require a stable input supply within ±10% and isolated output power. It operates with low noise and ripple and supports compact PCB mounting. The B0509S module is available in a miniature SIP/DIP package and uses an industry standard pinout.
