RP516x No.EA-518-190325 TYPICAL APPLICATION CIRCUIT VIN VOUT VIN LX L RP516x 2.2 µH C VOUT IN COUT 10 µF 22 µF CE GND RP516x Typical Application CircuitPrecautions for Selecting External Components ・Using ceramic capacitors with low ESR (Equivalent Series Resistance) are recommended. Select capacitors with bias characteristics and input/output voltages taken into consideration. ・When a built-in Lx switch is turned off, a spike-like high voltage may be generated due to an inductor. COUT voltage resistance should be 1.5 times or more than the set output voltage. ・Select an inductor having small DC resistance, sufficient allowable current and less possibility of causing magnetic saturation. 9
