NCP3170BDR2G Description

Short technical summary and product information.

The NCP3170BDR2G from On Semiconductor is a versatile 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 delivering a continuous output current of up to 3 A. This device features current mode control and integrates several functions internally, such as soft start, power good detection, and switching frequency, reducing the need for external components.

 

The regulator supports fixed PWM operation at 500 kHz and 1 MHz, with an adjustable output voltage as low as 0.8 V. It incorporates cycle-by-cycle current monitoring, short-circuit protection, and thermal shutdown for robust operation. The NCP3170BDR2G is housed in a compact 8-SOIC package, suitable for surface mount applications.

 

Typical applications for the NCP3170BDR2G include point-of-load DC/DC converters, set-top boxes, DVD/Blu-ray drives, LCD monitors and TVs, cable modems, and telecom/networking equipment. Its design prioritizes efficiency and reliable performance in demanding electronic systems.
