NCP3102C Datasheet | onsemi

Wide Input Voltage Synchronous Buck Converter The NCP3102C is a high efficiency, 10 A DC--DC buck converter designed to operate from a 5 V to 12 V supply. The device is capable of producing an output voltage as low as 0.8 V. The NCP3102C can continuously output 10 A through MOSFET switches driven by an internally set 275 k Hz oscillator. The 40--pin device provides an optimal level of integration to reduce size and cost of the power supply. The NCP3102C also incorporates an externally pensated transconductance error amplifier and a capacitor programmable soft--start function. Protection Features include programmable short circuit protection and input under voltage lockout (UVLO). The NCP3102C is available in a 40--pin QFN package.
