Step-Up DC/DC Converter

High Efficiency PFM

ST1638

DESCRIPTION

The ST1638 is a high efficiency PFM step-up DC/DC converter for application using

battery powered devices. Only three external components are required to construct a low ripple,

high efficiency converter. ST1638 can start up from 0.9V input voltage with 1mA load.

The space saving SOT-89 and SOT-23 packages make ST1638 an ideal choice for spce

conscious applications.
