RICOH RP502x SERIES handbook

Update: 30 September, 2023

The RP502x Series are low supply current CMOS-based PWM/VFM step-down DC/DC converters with synchronous rectifier. RP502x can be selected from two control types - fixed PWM control or PWM/VFM auto switching control in which mode automatically switches to high-efficiency VFM mode in low output current. RP502x includes a soft start circuit, an under-voltage lockout circuit (UVLO), and a latch protection circuit. By simply using an inductor and capacitors as external components, a high-efficiency step-down DC/DC converter can be easily configured. The small inductor (1.0μH/2.2μH) and small output capacitor (4.7μF) can be used by the switching of 3.3MHz.
