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
