LTC1159CS-5#TRPBF

DC DC Switching Controllers Overview

The LTC1159CS-5#TRPBF is a high-efficiency synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 40 V and provides a fixed 5 V output capable of delivering up to 10 A when paired with external power MOSFETs. The device integrates a 250 kHz switching frequency, achieving a typical load regulation of 60 mV and an operating supply current of 200 uA. It features a shutdown mode and is housed in a 16-lead SOIC package.
