Ricoh RP500x Series Step-Down DC/DC Converter Datasheet
The RP500x Series consists of CMOS-based 600mA step-down DC/DC converters with synchronous rectifiers. Each IC integrates an oscillator, switching control circuit, reference voltage unit, error amplifier, soft-start circuit, protection circuits, UVLO circuit, and switching transistors. A low ripple, high-efficiency converter can be easily composed using this IC along with only an inductor and capacitors.
The series features built-in feedback resistors that fix the output voltage internally, allowing 0.1V step adjustments via laser trim. It supports automatic mode alternative circuits for improved efficiency or fixed PWM control. Protection includes a current limit circuit and a latch-type protection circuit. The IC is available in WLCSP-6-P2, DFN1616-6, DFN(PLP)1820-6, and SOT-23-6W packages.
