ADVANCED INFORMATION

AIC1594

1A STEP-DOWN PWM REGULATOR

SPEC NO: DS-1594-P1 03/23/00

DESCRIPTION

FEATURES

Operating Input Voltage From 4.5V to 36V

The AIC1594 series are step-down monolithic

PWM regulators delivering 1A 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.

2.5V, 3.3V, 5V , 12V and Adjustable Output Ver-

sion

Adjustable Version Output Voltage Range , 1.25V

to 30V ± 4% max Over Line and Load Regulation

Available in TO220-5 and TO263-5 Package

Requires Only 4 External Components.

150KHz/300KHz Fixed Constant Frequency

Low Power Standby Mode, I_QTypically 80µA

TTL Shutdown Capability.

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.

Output Overvoltage Protection

Current Limit and Thermal Shutdown Protection.

1A Guaranteed Output Current

The internal precious reference combined with

voltage feedback loop provides optimum output

voltage accuracy and fast load transient response.

APPLICATIONS

Simple High Efficiency Step-down regulator

Packages available are in standard SOT89-5

and DIP8 for standard assembly and TO263-5,

SOP8 for SMD.
