LTC1430

Linear Technology introduces the LTC1430 switching regulator controller for high power 5V step-down applications where efficiency, output voltage accuracy and board space requirements are critical. The LTC1430 is designed to be configured as a synchronous buck converter with a minimum of external components. It runs at a fixed switching frequency (nominally 200kHz) and provides all timing and control functions, adjustable ...
