产品概要

描述

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 VINas low as 1.5 V and device supply voltage in the range of 5 V to 12 V.

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.

The A6727 provides programmable overcurrent protection as well as over and undervoltage protection. The current information is monitored across the low-side MOSFET RDS(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.
