onsemi NCP3101C
The NCP3101C is a high efficiency, 6 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 NCP3101C can continuously output 6 A through MOSFET switches driven by an internally set 275 kHz oscillator.| Part No. | NCP3101C |
