The AN8017SA is a two-channel PWM DC-DC converter control IC that features low-voltage operation. This IC can obtain the step-up voltage with a small number of external components. The minimum operating voltage is as low as 1.8 V so that it can operate with two dry batteries. In addition, since it uses the 16-pin surface mounting type package with 0.65 mm pitch, it is suitable for a miniaturized highly efficient potable power supply.
