USP10B – XC9136 – K
Description
1A Driver Transistor Built-in, Step-Up DC/DC Converters with Load Disconnection Function
XC9136 series are synchronous step-up DC/DC converters with a 0.2Ω(TYP.) N-ch driver transistor and a 0.2Ω(TYP.) synchronous P-ch 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 33Ω load 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 fixed output voltage has 1.8~5.0V (±2.0% accuracy) output voltage range with 0.1V increments.
