1 / 14 page  May 2007 Rev. 3 1/14 14 ST763A series 3.3V Step down current mode PWM DC-DC converters Features ■ 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 efficiency: 90% ■ Operating temperature range: -40°C to 85°C ■ Available in SO-8 package 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 device are cycle-by-cycle 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 is SO-8. Typical application are in 5V to 3.3V converters, cellular phones, portable instruments, hand-held computers, and peripherals. SO-8 www.st.com Order code Part number Packaging ST763AC ST763ACDTR |
