Linear Technology LTC1474
The LTC1474 uses logic-controlled shutdown while the LTC1475 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 for moderate current (up to 300mA) battery-powered applications.| Part No. | LTC1474 |

DESCRIPTION
The LT C®1474/LTC1475 series are high efficiency stepdown converters with internal P-channel MOSFET power switches that draw only 10µA typical DC supply current at no load while maintaining output voltage. 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
