SC1631 Datasheet (Semtech Corporation) - LOW VOLTAGE STEP-UP DC-DC CONVERTER

SC1631, LOW VOLTAGE STEP-UP DC-DC CONVERTER

The SC1631 is a high efficiency step up DC-DC converter.

Only four external components are required to deliver a fixed voltage of 3V, 3.3V, or 5V.

Efficiency beyond 87% can be easily achieved at 100mA load with 2.2V to 3V input voltages.

A logic-controlled shutdown mode is provided for power saving.
