LTC1474CMS8-5 | Low Q-Current High Efficiency Switching Regulator, 5V Fixed @ 300mA
Analog Devices Inc.The LTC1474/LTC1475 series are high efficiency step-down converters with internal P-channel MOSFET power switches that draw only 10?A typical DC supply current at no load while maintaining output voltage. The LTC1474 uses logic-controlled shutdown while the LTC1475 features pushbutton on/off. The low supply current coupled with Burst Mode? 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 for moderate current (up to 300mA) battery-powered 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 low-battery detector that remains functional in shutdown is provided . The LTC1474/LTC1475 series availability in 8-lead MSOP and SO packages and need for few additional components provide for a minimum area solution.Applications Cellular Telephones and Wireless Modems 4mA to 20mA Current Loop Step-Down Converter Portable Instruments Battery-Operated Digital Devices Battery Chargers Inverting Converters Intrinsic Safety Applications
