TECHNICAL DATA

3.0 A, 15 V, Step-Down

Switching Regulator

IL2576-xx

The IL2576 series of regulators are monolithic integrated

circuits ideally suited for easy and convenient design of a step–

down switching regulator (buck converter). All circuits of this series

are capable of driving a 3.0 A load with excellent line and load

regulation. These devices are available in fixed output voltages of

3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version.

TO-220-5L

These regulators were designed to minimize the number of

external components to simplify the power supply design. Standard

series of inductors optimized for use with the IL2576 are offered by

several different inductor manufacturers. Since the IL2576

converter is a switch–mode power supply, its efficiency is

significantly higher in comparison with popular three–terminal

linear regulators, especially with higher input voltages. In many

cases, the power dissipated is so low that no heatsink is required

or its size could be reduced dramatically.

TO-263-5L

A standard series of inductors optimized for use with the

IL2576 are available from several different manufacturers. This

feature greatly simplifies the design of switch–mode power

supplies. The IL2576 features include a guaranteed ±4% tolerance

on output voltage within specified input voltages and output load

conditions, and ±10% on the oscillator frequency (±2% over 0°C to

125°C). External shutdown is included, featuring 80 ㎂ (typical)

standby current. The output switch includes cycle–by–cycle current
