Onsemi NCP4060A | Demoboard NCP4060AGEVB

Description

The NCP4060 is a high performance, high voltage, high efficiency, fully integrated, voltage−mode synchronous buck converter with constant frequency voltage mode control with input feedforward architecture. It operates from input voltages ranging from 16 V to 80 V and it is capable of generating output voltages down to 1.25 V at 6 A DC loads and up to 10 A peak load currents, across a wide range of ambient temperatures. The NCP4060 exhibits protection features that protect the load from faults like over−voltage, over−current and over−temperature. The NCP4060 adopts a ±1% accurate reference voltage to maintain a tight−regulated output voltage. It has a programmable switching frequency that can be set from 100 to 500 kHz.
