Description
LTC1474/LTC1475 Low Quiescent Current High Efficiency Step-Down Converters .
The LT C®1474/LTC1475 series are high efficiency stepdown converters with internal P-channel MOSFET power switches that draw only 10µA typical DC supp.
Features
* pushbutton on/off. The low supply current coupled with Burst ModeTM operation enables the LTC1474/LTC1475 to maintain high efficiency over a wide range of loads. These features, along with their capability of 100% duty cycle for low dropout and wide input supply range, make the LTC1474/LTC1475 ideal
Applications
* The peak switch current is user-programmable with an optional sense resistor (defaults to 325mA minimum if not used) providing a simple means for optimizing the design for lower current applications. The peak current control also provides short-circuit protection and excellent startup behavior. A l
