RP401x Series
PWM/VFM Step-up DC/DC Converter
The RP401x Series are CMOS-based PWM/VFM step-up DC/DC converters which can start-up from Typ. 0.6V. RP401K 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.) RP401x includes a soft start circuit. By simply using an inductor, a capacitor, a diode, and (resistors) 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(PLP)1820-6 package is also available.
