DESCRIPTION
The LX2172/73 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 LX2172/73 are optimized for boost and flyback applications, but can also be used in forward and inverting converter configuations.
