Frequently asked questions

What is the step size for output voltage setting?

The output voltage can be set stepwise with a step of 0.1V.

What are the two choices of basic oscillator frequency?

The series offers 100kHz for xx2C models and 180kHz for xx2D models.

What external components are required to compose a converter?

A low ripple, high efficiency step-up DC/DC converter can be composed with only four external components: an inductor, a diode, a transistor, and a capacitor.
