Overview

Topology	Buck Converter
Input voltage	4.5-18 V
Switching frequency	1000 kHz
Output 1	5 V / 3 A
IC revision	2

Description

The NCP3170 is a flexible synchronous PWM Switching Buck Regulator. The NCP3170 operates from 4.5 V to 18 V, producing 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.
