AN8049FHN
1.8-volt 3-channel step-up, step-down, and polarity inverting
DC-DC converter control IC
s 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.
s Features
• Wide operating supply voltage range: 1.8 V to 14 V
• High-precision reference voltage circuit
— VREF pin voltage: ±1%
— Error amplifier:
±1.5%
• Ultrathin surface mounting package for miniaturized and thinner power supplies
Package: QFN-24
0.5-mm lead pitch
5.4 mm
× 4.4 mm × t 0.8 mm
• 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
CC −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.
• Timer latch short-circuit protection circuit (charge current: 1.1 µA typical)
• Low input voltage malfunction prevention circuit (U.V.L.O.)
(operation start voltage: 1.67 V typical)
• Standby function (active-high control input, standby mode current: 1 µA maximum)
s Applications
• Electronic equipment that requires a power supply system
