概述

The RP401 Series are CMOS-based PWM/VFM step-up DC/DC converters which can start-up from Typ. 0.6V. RP401 can be switched from two control types by inputting signal to the MODE pin - fixed PWM control or PWM/VFM auto switching control in which mode automatically switches to high-efficiency VFM mode in low output current. (RP401N Series can be selected from fixed PWM control or PWM/VFM auto switching control.) RP401 includes a soft start circuit. By simply using an inductor, a capacitor, (resisters for adjustable type), and a diode as external components, a high-efficiency step-up DC/DC converter can be easily configured. The output voltage can be selected from the internally fixed or the externally adjustment. In addition to SOT-23-5 package, a 1.8mm × 2.0mm square DFN(PL)1820-6 package is also available.
