A6727

Single-phase PWM controller for automotive applications

Datasheet

- production data

Applications

•

Dedicated to automotive applications

Description

The A6727 is a single-phase step-down controller

with integrated high-current drivers that provides

complete control logic, protection and reference

voltage to realize a general DC-DC converter by

using a compact SO-8 package. The device

flexibility allows the management of conversions

with power input V_INas low as 1.5 V and device

supply voltage in the range of 5 V to 12 V.

SO-8

Features

The A6727 provides simple control loop with

voltage mode error-amplifier. The integrated 0.8 V

reference allows the regulation of output voltages

with 1% accuracy over line and temperature

variations. The oscillator is internally fixed to 300

kHz.

High-current integrated drivers

Adjustable output voltage

0.8 V internal reference

The A6727 provides programmable overcurrent

protection as well as over and undervoltage

protection. The current information is monitored

across the low-side MOSFET R_DS(on)saving the

use of expensive and space-consuming sense

resistors while output voltage is monitored

through FB pin.

FB disconnection protection prevents excessive

and dangerous output voltages from floating FB

pin.
