Low Quiescent Current High Efficiency Step-Down Converters

The LTC1474 LTC1475 series are high efficiency step- Down Converters with internal P-Channel MOSFET power switches that draw only 10A typical DC supply current at no load while maintaining output voltage. The LTC1474 uses logic-controlled shutdown while the LTC1475 fea- tures pushbutton on/off. The low supply current coupled with Burst Mode operation enables the LTC1474 LTC1475 to maintain high effi- ciency 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.
