About this manual

The RP401x Series are CMOS-based PWM/VFM step-up DC/DC converters capable of starting up from a typical 0.6V input. These devices can be configured using an inductor, capacitor, diode, and resistors to create a high-efficiency converter. The output voltage can be selected either from internally fixed levels or adjusted externally via a feedback voltage of 0.6V.
