The RP503x series is a low supply current CMOS-based PWM/VFM step-down DC/DC converters with synchronous rectifier. RP503x is PWM/VFM auto switching control in which mode automatically switches to high-efficiency VFM mode in low output current. The efficiency in low output current (VFM mode) improved compared with existing products. RP503x 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.
