NCP3102

NCP3102 Wide Input Voltage Synchronous Buck Converter The NCP3102 is a high efficiency, 10 A DC-DC buck converter designed to operate from a 5 V to 13.2 V supply. The device is capable of producing an output voltage as low as 0.8 V. The NCP3102 can continuously output 10 A through MOSFET switches driven by an internally set 275 kHz oscillator. The 40-pin device provides an optimal level of integration to reduce size and cost of the power supply. The NCP3102 also incorporates an externally compensated transconductance error amplifier and a capacitor programmable soft-start function. Protection features include programmable short circuit protection and under voltage lockout (UVLO). The NCP3102 is available in a 40-pin QFN package.
