Description
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 GUARAN.
The ST763A is a step-down switching regulator .
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 ex
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. SCHEMATIC DIAGRAM
