NCP5173

1.5 A 560 kHz−1.0 MHz

Boost Regulator

The NCP5173 is a switching regulator with a high efficiency, 1.5 A

integrated switch. It runs at a base frequency of 560 kHz and can be

synchronized to an external clock up to 1.0 MHz. This part operates

over a wide input voltage range, from 2.7 V to 30 V. The flexibility of

the design allows the chip to operate in most power supply

configurations, including boost, flyback, forward, inverting, and

SEPIC. The IC uses current mode architecture, which allows excellent

load and line regulation, as well as a practical means for limiting

current. Combining high frequency operation with a highly integrated

regulator circuit results in an extremely compact power supply

solution. The circuit design includes provisions for features such as

frequency synchronization, shutdown, and feedback controls for

positive voltage regulation.
