1.8-volt 3-channel step-up, step-down, and polarity inverting
DC-DC converter control IC
1
I
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.
And also, it is housed in an ultrathin, 4-directional-
lead SMD-package whose thickness is 0.8 mm maximum
and pin-pitch is 0.5 mm therefore it is most suitable for
making a power supply small and thin.

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

1.4 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.
