TECHNICAL DATA
1.0 A, 15 V, Step-Down
Switching Regulator
The IL2575 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 1.0 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.
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 IL2575 are offered by
several different inductor manufacturers. Since the IL2575
converter is a switch–mode power supply, its efficiency is

popular three–terminal
input voltages. In many
cases, the power dissipated is so low that no heatsink is required
or its size could be reduced dramatically.
A standard series of inductors optimized for use with the
IL2575 are available from several different manufacturers. This
feature greatly simplifies the design of switch–mode power
supplies. The IL2575 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
limiting, as well as thermal shutdown for full protection under fault
conditions.
