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.
2µA OFF MODE SWITCH ON/OFF CONTROL TYPICAL EFFICENCY: 90% OPERATING TEMPERATURE RANGE: -40°C TO 85°C AVAILABLE IN SO-8 AND DIP-8 PACKAGES DIP-8 SO-8 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.
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, under voltage lockout and programmable soft-start protection.
A 22µH 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.
