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 c.

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. 8.20 0.08 .
