XC9140A331MR-G
Step-Up Synchronous PFM DC/DC Converter, 3.3V 295mA SOT-25
Product Overview
The XC9140 series are step-up synchronous DC/DC converters that support ceramic capacitors and have an internal 0.6? (TYP.) Nch driver transistor and an internal 0.65? (TYP.) Pch synchronous rectifier switch transistor. PFM control enables a low quiescent current, making these products ideal for portable devices that require high efficiency. When the output voltage is 3.3V and the load current is 1mA (XC9140Axx1 type and XC9140Cxx1 type), startup from an input voltage of VIN = 0.9V is possible which means that these products can be used in applications that start using a single alkaline or nickel-metal hydride battery. The output voltage can be set from 1.8V to 5.0V (
