LM26001

1.5A Switching Regulator with High Efficiency Sleep

Mode

General Description

Features

n High efficiency sleep mode

n 40 µA typical Iq in sleep mode

n 10 µA typical Iq in shutdown mode

n 3.0V minimum input voltage

n 4.0V to 38V continuous input range

n 1.5% reference accuracy

n Cycle-by-cycle current limit

n Adjustable Frequency (150 kHz to 500 kHz)

n Synchronizable to an external clock

n Power Good Flag

The LM26001 is a switching regulator designed for the high

efficiency requirements of applications with stand-by modes.

The device features a low-current sleep mode to maintain

efficiency under light-load conditions and current-mode con-

trol for accurate regulation over a wide input voltage range.

Quiescent current is reduced to 10 µA typically in shutdown

mode and less than 40 µA in sleep mode. Forced PWM

mode is also available to disable sleep mode.

The LM26001 can deliver up to 1.5A of continuous load

current with a fixed current limit, through the internal

N-channel switch. The part has a wide input voltage range of

4.0V to 38V and can operate with input voltages as low as

3V during line transients.

n Forced PWM function

n Adjustable Soft-start

n TSSOP-16 exposed pad package

n Thermal Shut Down

Operating frequency is adjustable from 150 kHz to 500 kHz

with a single resistor and can be synchronized to an external

clock.

Other features include Power good, adjustable soft-start, Applications

enable pin, input under-voltage protection, and an internal

bootstrap diode for reduced component count.

n Automotive Telematics

n Navigation systems

n In-Dash Instrumentation

n Battery Powered Applications

n Stand-by power for home gateways/set-top boxes
