1.25a High-efficiency 100khz Switching Regulator

The LX2172 LX2173 are fixed-frequency, current-mode Switching Regulator integrated circuits. These ICs contain all necessary control circuitry plus a 1.25A on-board Transistor to design a complete DC:DC Switching Regulator with minimum external components. All functions are integrated into a single IC, available in 8-pin DIP and SOIC or a 5- pin TO-220 power package, making them extremely easy to design with and use. The LX2172 LX2173 are optimized for boost and flyback applications, but CAN also be used in forward and inverting converter configuations. The LX2172 CAN be connected to an external Clock for synchronization, and CAN enter micropower operation when the VC pin is pulled low. The LX2173 has an enable function, which permits extremely low micropower operation, consuming under 10A current when the ENABLE pin is brought low By Microsemi Corporation
