NCP3170ADR2G Description

Short technical summary and product information.

The ON Semiconductor NCP3170ADR2G is a flexible synchronous PWM switching buck regulator designed for efficient power conversion. It operates within an input voltage range of 4.5 V to 18 V, capable of sourcing up to 3 A of continuous output current. This device features current mode control and integrates several components, including soft start, power good detection, and switching frequency, reducing external component count.

 

The NCP3170ADR2G operates at a fixed switching frequency of 500 kHz or 1 MHz, offering flexibility in design. It provides 1.5% initial output accuracy and includes internal protection features such as short-circuit protection and thermal shutdown. The regulator is designed to turn on into pre-bias conditions and offers light load efficiency.

 

This switching regulator is housed in an 8-SOIC package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA), making it suitable for various environmental conditions. Typical applications include point-of-load DC/DC converters, set-top boxes, LCD monitors, and telecom equipment.
