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.
