This document discusses the applications of the LT1300 and LT1301 micropower DC/DC converter ICs. These converters offer flexible and cost-effective design solutions for battery-powered equipment requiring high efficiency, space efficiency, and micropower power solutions.
The document introduces the LT1300 and LT1301 micropower DC/DC converter ICs, which are designed to improve electrical and physical efficiency in battery-based power supply designs. These devices feature a 1A on-chip switch with a low saturation voltage of 170mV and utilize Burst Mode operation to maintain high efficiency across the full load range.
| Internal oscillator frequency | 155kHz |
|---|---|
| Quiescent current (fully operating) | 120uA |
| Shutdown current | 10uA |
| Package types | 8-lead DIP or SOIC |
The fully operating quiescent current is only 120uA.
Shutdown is effected by taking the SHUTDOWN pin high, which reduces Vin current to 10uA.
The switch current is nominally set at 1A, which can be reduced to approximately 400mA via the IL pin.
