! DESCRIPTION
The AIC1595 series are step-down monolithic
PWM regulators delivering 2A at fixed voltages of
2.5V , 3.3V, 5.0V , 12V and using a external di-
vider to adjust output voltage from 1.25V to 30V
with excellent line and load regulation.
Switching frequency up to 150KHz/300KHz are
achievable thus allowing smaller sized filter com-
ponents. Internal current limit and thermal shut-
down circuits provide protection from overloads. It
also provides output overvoltage and short pro-
tection under fault conditions.
The internal precious reference combined with
! APPLICATIONS
voltage feedback loop provides optimum output
voltage accuracy and fast load transient response.
" Simple High Efficiency Step-down regulator
" On-Card Switching regulators
Packages available are in standard TO220-5 for
" Fixed Voltage power supply for LCD Monitor
standard assembly and TO263-5 for SMD.
