Overview
e e DC-DC Converter Controller for Digital Still Camera / AN30210A h S a ! Overview at .
D w w w Pursuing low power consumption and high efficiency by New Generation CMOS process The AN30210A is a DC-DC converter control IC that features lowvoltage 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.
