■GENERAL
DESCRIPTION
☆GreenOperation
Compatible
XC9265 series are Ultra Low Power synchronous-rectification type PFM step down DC/DC converters with a built-in 0.4Ω
(TYP.) Pch driver and 0.4Ω (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, C
IN
and C
L
capacitors are needed as external parts to make a step down DC/DC circuit.
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
L
capacitor during stand-by mode due to the internal resistance by turning
on the internal switch between V
OUT
-GND. This enables output voltage restored to GND level fast.
