XC9265Series  
ETR05053-004  
Ultra Low Power Synchronous Step-Down PFM DC/DC Converter  
GreenOperation Compatible  
GENERAL DESCRIPTION  
XC9265 series are Ultra Low Power synchronous-rectification type PFM step down DC/DC converters with a built-in 0.4  
(TYP.) Pch driver and 0.4(TYP.) Nch synchronous switching transistor, designed to allow the use of ceramic capacitor.  
PFM control enables a low quiescent current, making these products ideal for battery operated devices that require high  
efficiency and long battery life.  
Only inductor, CIN and C capacitors are needed as external parts to make a step down DC/DC circuit.  
L
Operation voltage range is from 2.0V to 6.0V. This product has fixed output voltage from 1.0V to 4.0V(accuracy: ±2.0%) in  
increments of 0.05V.  
During stand-by, all circuits are shutdown to reduce consumption to as low as 0.1μA(TYP.) or less.  
With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel MOS driver transistor is forced OFF when input  
voltage gets lower than UVLO detection voltage. Besides, XC9265 series has UVLO release voltage of 1.8V (Typ.).  
The product with C  
L
discharge function can discharge C capacitor during stand-by mode due to the internal resistance by turning  
L
on the internal switch between VOUT -GND. This enables output voltage restored to GND level fast.
