XT1712 PWM/PFM Automatic Switching Controlled Synchronous DC-DC Converters

XT1712 series is a group of high efficiency synchronous-rectification type buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version and fixed output voltages. Automatic PWM/PFM mode operation increases efficiency and decreases output voltage ripple at light loads, further extending battery life. S.
