Overview
The AN8049FHN is a three-channel PWM DC-DC
converter control IC that features low-voltage operation.
This IC can form a power supply that provides two step-
up outputs and one step-down or polarity inverted output
with a minimal number of external components. Minimal
operating supply voltage of this IC is as low as 1.8 V, so
that it can operate from 2 dry-batteries.

QFN024-P-0405A (Lead-free package)
Ultrathin surface mounting package for miniaturized
and thinner power supplies
Supports control over a wide output frequency range: 20 kHz to 1 MHz
On/off (sequence control) pins provided for each channel for easy sequence control setup
The negative supply error amplifier supports 0-volt input.
Common-mode input voltage range:
0.1 V to V

This allows the number of external components to be reduced by two resistors.
Fixed duty factor: 86%
However, the duty can be adjusted to anywhere from 0% to 100% with an external resistor.
