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 features are typical efficiency of 90%, quiescent current of 0.6mA, and only 0.2A in shut-down.

The PWM current mode control provides precise output regulation and very good transient response. ST763A 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 ST763A are cycle-by-clicle current limiting, overcurrent limiting, under voltage lockout and programmable soft-start protection. A 22H inductor works in most applications, so no sophisticated design is necessary.

Package available are SO-8 and DIP-8. Typical application are in 5V to 3.3V converters, cellular phones, portable instruments, hand-held computers, and peripherals.
