PT1301 DC DC Converter


The PT1301 is a compact, high efficiency, and low voltage step-up DC/DC converter with an Adaptive Current Mode PWM control loop. It comprises of an error amplifier, a ramp generator, a PWM comparator, a switch pass element and the driver. It provides stable and high efficient operation over a wide range of load currents without external compensation.

The output voltage is set with two external resistors. The 500KHz high switching rate reduces the size of external components.
