RICOH RP505K SERIES DATA SHEET

Update: 30 September, 2023

RP505K series are low supply current CMOS-based PWM/VFM step-down DC/DC converters with synchronous rectifier. RP505K can be selected from two control types by input signal to the MODE pin - forced PWM control or PWM/VFM auto switching control in which mode automatically switches to high-efficiency VFM mode in low output current. The xx1A/B version with an internally fixed output voltage type and the 001C version with an externally adjustable output voltage type are available. RP505K includes a soft start circuit, an under-voltage lockout circuit (UVLO), thermal shutdown circuit and a latch protection circuit. By simply using an inductor, (resistors) and capacitors as external components, a high-efficiency step-down DC/DC converter can be easily configured. The small inductor (2.2μH) and output capacitor (10μF) can be used by the switching of 2.25MHz. A 2mm square compact DFN(PLP)2020-8 package is available.
