NCP3125
4 A Synchronous PWM
Switching Converter
The NCP3125 is a flexible synchronous PWM Switching Buck
Regulator. The NCP3125 is capable of producing output voltages as
low as 0.8 V. The NCP3125 also incorporates voltage mode control.
To reduce the number of external components, a number of features
are internally set including switching frequency. The NCP3125 is
currently available in an SOIC ? 8 package.
