A5970D

Up to 1 A step down switching regulator

for automotive applications

Features

■ Qualified following the AEC-Q100

requirements (see PPAP for more details)

■ 1 A DC output current

SO8

■ Operating input voltage from 4 V to 36 V

■ 3.3 V / ( 2%) reference voltage

■ Output voltage adjustable from 1.235 V to V

■ Low dropout operation: 100% duty cycle

■ 250 kHz Internally fixed frequency

■ Voltage feedforward

Description

The A5970D is a step down monolithic power

switching regulator with a minimum switch current

limit of 1.35 A so it is able to deliver up to 1 A DC

current to the load depending on the application

conditions. The output voltage can be set from

■ Zero load current operation

1.235 V to V .

■ Internal current limiting

The device uses an internal p-channel DMOS

■ Inhibit for zero current consumption

■ Synchronization

transistor (with a typical R

of 250 mΩ) as

DS(on)

switching element to minimize the size of the

external components.

■ Protection against feedback disconnection

■ Thermal shutdown

An internal oscillator fixes the switching frequency

at 250 kHz. Having a minimum input voltage of

4 V only it fits the automotive applications

requiring the device operation even in cold crank

conditions. Pulse by pulse current limit with the

internal frequency modulation offers an effective

constant current short circuit protection.

Application

■ Dedicated to automotive applications
