DS1227 Description

The DS1227 Kickstarter is a unique CMOS circuit which bines power conversion and microenergy management functions for battery operated systems. Using its integral DC-DC converter, the DS1227 supplies +5V on demand from either a 3 or 6 volt battery input. The primary +5V output, typically tied to the microcontroller’s VCC pin, is “kickstarted” on in response to any one of several possible momentary, external signal...
