Analog Devices LTC3203EDD-1#PBF Charge Pump, Regulator 500mA, 4.5 V, 1 MHz 10-Pin, DFN

The Linear Technology range of Inductorless DC/DC Converter (Charge Pump) offers step-up, step-down as well as inverting devices. The regulated buck boost charge pumps and the regulated Inverting charge pumps contain Spread Spectrum technology on-chip making the input and output quieter.

Small footprint due to no inductor
Simple design

Switching Voltage Regulators, Linear Technology

Linear Technology product series of synchronous and non-synchronous internal switching regulator ICs offer high efficiency plus a wide input voltage range and switching frequencies up to 4MHz.
The controllers span over several types of configurations from buck (step-down), boost (step-up), buck-boost, forward, Isolated, Inverting and flyback controllers. The Flyback, Forward and Isolated Controllers primary and secondary side provide a solution to help replace the DC/DC bricks that get used in back-plane power conversion.
