NCP3170
Synchronous PWM Switching Converter
The NCP3170 is a flexible synchronous PWM Switching Buck Regulator. The NCP3170 operates from 4.5 V to 18 V, sourcing up to 3 A and is capable of producing output voltages as low as 0.8 V. The NCP3170 also incorporates current mode control. To reduce the number of external components, a number of features are internally set including soft start, power good detection, and switching frequency. The NCP3170 is currently available in an SOIC−8 package.
Features

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
1. The maximum package power dissipation limit must not be exceeded.
PD= [TJ(max) - TA] / RθJA
2. The value of JA is measured with the device mounted on 2in x 2in FR−4 board with 2oz. copper, in a still air environment with TA = 25°C. The value in any given application depends on the user’s specific board design.
3. 60−180 seconds minimum above 237°C.
