Product Summary
The LTC3406ES5#TRPBF is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version and fixed output voltages of 1.5V and 1.8V. Supply current during operation is only 20µA and drops to ≤1µA in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3406ES5#TRPBF ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. Automatic Burst Mode operation increases efficiency at light loads, further extending battery life. The applications of the LTC3406ES5#TRPBF include Cellular Telephones, Personal Information Appliances, Wireless and DSL Modems, Digital Still Cameras, MP3 Players and Portable Instruments.
