Overview
The AN8017SA is a two-channel PWM DC-DC con-
verter 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.

Incorporating an under-voltage lock-out circuit (U.V.L.O.)
(circuit operation-starting voltage: 1.67 V typical)
Dead-time is variable
Flatness of switching current can be obtained by staggering the turn-on timing of each channel
Built-in unlatch function
When DT1 pin is low level or DT2 pin is high level, independent turn-off is possible.
