DESCRIPTION
The LTC®3252 is a switched capacitor step-down DC/DC converter that produces two adjustable regulated outputs from a single 2.7V to 5.5V input. The part uses switched capacitor fractional conversion to achieve a typical efficiency increase of 50% over that of a linear regulator. No inductors are required.
