New publication, effective from Mar.30.2001
Pursuing low power consumption and high efficiency by New Generation CMOS process
DC-DC Converter Controller for Digital Still Camera / AN30210A
!
Overview
The AN30210A is a DC-DC converter control IC that features low-
voltage operation and has a 5 V output channel applicable for self
bias and six output channels as PWM DC-DC converter control.
This IC is composed of three step-up outputs, one step-down
output, one inverted output and two outputs for a transformer drive.
Minimal operating supply voltage of this IC is as low as 1.5 V,so
that it can operate with 2 dry-batteries.
A high precision reference voltage of
±
1% tolerance is obtained
by using synchronized operation for all channels and synchronized
rectification on the output circuit of step-down voltage.
Direct MOSFET drive is available.
