Part Number : LTC3245
Function : Wide Vin range, Low Noise, 250mA Buck-Boost Charge Pump
Package : DFN 12 Pin Type
Maker : Linear Technology
Pinouts : 
Description :
The LTC3245 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. Internal circuitry automatically selects the conversion ratio to optimize efficiency as input voltage and load conditions vary.
