LTC3245 Datasheet (Analog Devices) - 250mA Buck-Boost Charge Pump

LTC3245, 250mA Buck-Boost Charge Pump

The LTC®3245 is a switched capacitor buck-boost DC/DC converter that produces a regulated output (3.3V, 5V or adjustable) from a 2.7V to 38V input.

The device uses switched capacitor fractional conversion to maintain regulation over a wide range of input voltage.
