■GENERAL
DESCRIPTION
XC9135/XC9136 series are synchronous step-up DC/DC converters with a 0.2Ω(TYP.) N-channel driver transistor and a 0.2
Ω(TYP.)
synchronous P-channel switching transistor built-in. A highly efficient and stable current can be supplied up to 1.0A by
reducing ON resistance of the built-in transistors.
The series are able to start operation under the condition which has 0.9V input voltage to generate 3.3V output voltage with a 33
Ωload
resistor, suitable for mobile equipment using only one Alkaline battery or one Nickel metal hydride battery.
During the operation of a shutdown, the load disconnection function enables to cut the current conduction path from the input to
the output.
The output voltage is selectable in 0.1V increments within 1.8~5.0V (±2.0% accuracy).
The UVLO function of the XC9135 series is capable to reduce leaking potassium hydroxide by stopping IC operation while
battery voltage is declining. The release voltages of UVLO are 0.85V (±6.0% accuracy) and 1.6V (±3.0% accuracy), and
selectable voltages range of 0.9V~3.0V.

* The dissipation pad for the USP-10B package should be solder-plated in recommended mount pattern and metal masking so as to enhance
mounting strength and heat release.
If the pad needs to be connected to other pins, it should be connected to the AGND (No.8) or PGND (No.9) pin.
*Please short the GND pins (pins 8 and 9).
