GENERAL DESCRIPTION
The AIC2510 series are step-down monolithic
PWM converters for delivering 3A at fixed
voltages of 3.3V, 5.0V, 12V and using an
external divider to adjust output voltage from
1.2V to 30V with excellent line and load
regulation.
Switching frequency up to 150KHz is achievable
thus allowing smaller-sized filter components.
Internal current limit and thermal shutdown
circuits provide protection from overloads. The
internal
voltage
precise
accuracy
reference
and
fast
combined
load
with
voltage feedback loop provides optimum output
transient
response.
3A Guaranteed Output Load Current
APPLICATIONS
Fixed Voltage power supply for LCD Monitor
and LCD TV
On-Card Switching regulators
Simple High Efficiency Step-down regulator
