PT1101 Description
The PT1101 Series are CMOS-based PWM step-down DC/DC Controllers with low supply current. A low ripple, high efficiency step-down DC/DC converter can be easily posed of with additional several external ponents such as a power-transistor, an inductor, a diode and capacitors. Output voltage is fixed or can be adjusted with external resisters.
