PT1101 Datasheet (PowTech) - PWM/VFM Step-down DC-DC Controller

PT1101, PWM/VFM Step-down DC-DC Controller

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 composed of with additional several external components such as a power-transistor, an inductor, a diode and capacitors.

Output voltage is f
