RP500x SERIES  
step-down DC/DC Converters with synchronous rectifier  
NO.EA-155-080522  
OUTLINE  
The RP500X Series are CMOS-based step-down DC/DC Converters with synchronous rectifier.  
Each of these ICs consists of an oscillator, a switching control circuit, a reference voltage unit, an error  
amplifier, a soft-start circuit, protection circuits, UVLO circuit, switching transistors, and so on. A low ripple, high  
efficiency step-down DC/DC converter can be easily composed of this IC with only an inductor and capacitors. In  
terms of the output voltage, since the feedback resistances are built-in, the voltage is fixed internally.  
50mV(custom-made) step output can be set by laser-trim and 1.5% or 24mV tolerance depending on the output  
voltage is guaranteed.  
Mode alternative circuit works automatically for improving the efficiency. Considering fixed noise frequency,  
PWM fixed control type is also available. As protection circuits, the current limit circuit which limits peak current  
of Lx at each clock cycle, and the latch type protection circuit which works if the term of the over-current  
condition keeps on a certain time exist. The latch-type protection circuit works to latch an internal driver with  
keeping it disable. To release the condition of the protection, after disabling this IC with a chip enable circuit,  
enable it again, or restart this IC with power-on or make the supply voltage at UVLO detector threshold level or  
lower than UVLO.  
Since packages are DFN(PLP)1820-6, SOT23-6, WLCSP-6 (0.16φ), high density mounting on boards is  
possible.
