Product Overview

The LTC1474IS8#PBF is a high-efficiency Step-down Converter with internal P-channel MOSFET power switches that draw only 10µA typical DC supply current at no load while maintaining output voltage. The LTC1474 uses logic-controlled shutdown. The low supply current coupled with Burst Mode® operation enables the LTC1474 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 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 behaviour. A low-battery detector that remains functional in shutdown is provided.
  • Very low dropout operation - 100% Duty cycle
  • Low-battery detector functional during shutdown
  • Programmable current limit with optional current sense resistor (10 to 400mA typical)
  • Short-circuit protection
  • Few external components required
  • Over 92% possible high efficiency
  • Internal 1.4R power switch (VIN=10V)
  • 10µA Typical very low standby current
  • 6µA Typical active low micropower shutdown
