The device provides two synchronous buck controllers to implement mixed voltage systems and a flyback controller for 12V VPP generation for PCMCIA slots. The flyback architecture enables generation of high currents (150mA or more per slot) on the 12V bus for multiple slot PCMCIA applications. Each regulator can be independently switched off to fully isolate the load from the power supply.
