ML4880*
Portable PC/PCMCIA Power Controller
GENERAL DESCRIPTION
The ML4880 Portable PC and PCMCIA Power Controller is a complete solution for DC/DC power conversion for portable computing systems with single or multiple PCMCIA slots.
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 ...
