Product Information
Product Overview
LTC1879 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The input supply voltage range of 2.65V to 10V makes the device ideally suited for both single and dual Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. Burst Mode operation is inhibited during synchronization or when the SYNC/MODE pin is pulled low. The internal synchronous rectifier switch increases efficiency and eliminates the need for an external schottky diode. Low output voltages are easily supported with a 0.8V feedback reference voltage. It is widely used in application such as cellular telephones, portable computers, wireless modems etc.
