Manufacturer: STMicroelectronics

Overview: ST763A SERIES 3.3V STEP DOWN CURRENT MODE PWM DC-DC CONVERTERS s s s s s s s s s OUTPUT VOLTAGE 3.3V SUPPLY VOLTAGE RANGE FROM 3.3V TO 11V GUARANTEED OUTPUT CURRENT: 500mA TYPICAL OPERATION FREQUENCY: 200KHz VERY LOW QUIESCENT CURRENT: 0.6mA ON MODE 0.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The ST763A is a step-down switching regulator .

It operates from 3.3V to 11V giving a fixed 3.3V output voltage, delivering up to 500mA.

The mainly

Key Features

  • are typical efficiency of 90%, quiescent current of 0.6mA, and only 0.2µA in shut-down. The PWM current mode control provides precise output regulation and very good transient response. Output voltage accuracy is guaranteed to be ±5% over line, load and temperature variations. A minimum number of external components is used and the fixed frequency switching allows easy filtering of output ripple and noise. Other features of this ddevice are cycle-by-clicle current limiting, overcurrent limiting.
