The LTM4691 is a complete dual 2A output switching mode DC/DC power supply in a tiny 3mm × 4mm × 1.18mm LGA package. Included in the package are the switching controller, power FETs, inductors and all supporting components. Operating over an input voltage range of 2.25V to 3.6V, the LTM4691 supports two outputs with programmable output voltage range from 0.5V to 2.5V set by external resistors. Its high efficiency design delivers up to 2A continuous current on each output. Only bulk input and output capacitors are needed. It features forced continuous mode for low noise or Burst Mode operation for high efficiency at light loads.
