NCV33163PG is a DC-DC buck switching regulator which is designed to convert voltage to a regulated output voltage with higher current capacity. This regulator is specifically designed to reduce space requirements and simplify the circuit layout, allowing more efficiency and reliable power delivery. It can operate at a wide input voltage range between 4V to 28V and can provide an output voltage of 1.2V to 17V.

The NCV33163PG is suitable for applications ranging from consumer electronics, OC/IP Ethernet, automotive, industrial, and medical equipment. It is renowned for its excellent efficiency performance, wide input voltage range, low noise operation, output adjustable to 0.6V, remote on/off control, and protection features.

Working Principle

The NCV33163PG has been designed with the following features: an internal low on-resistance power switch that can deliver up to 6A, an integrated low dropout voltage regulator (LDO) with an output current capability of 2A, a wide input voltage range of 4V to 28V, and a wide output voltage range of 1.2V to 17V. The DC-DC buck converter has a pulse-width modulated (PWM) control and is designed to maintain a constant current regardless of input voltage or output voltage, allowing the power supply to achieve power conversion efficiency up to 95%. The switch is designed with internal current sensing pins that provide feedback to the control loop of the device, allowing it to achieve power conversion efficiency of up to 93%.

The NCV33163PG DC-DC switching regulator can operate in three different modes: continuous conduction mode (CCM), Discontinuous Conduction Mode (DCM), and Force Pulse-Width Modulation (PWM) mode. The operating mode can be selected through the use of an external switch or by setting the DIP switch. In addition to these features, the regulator also supports a wide range of external components and features, such as remote sensing, over-temperature protection, short-circuit protection and under-voltage lockout.

The regulator can be used with both synchronous and asynchronous MOSFETs and is easily configurable for use with either one. The regulator can be driven by a synchronous rectifier (SR) circuit, enabling low harmonic distortion and improved power efficiency. It can also be used in an asynchronous buck-builder circuit to utilize both a low dropout regulator and switching buck regulator in a single device.

In addition to the standard features, the device offers several advanced features, such as output under-voltage protection (UVP) and output over-voltage protection (OVP). These features are designed to limit the output voltage to a safe level, preventing damage to the load.

The NCV33163PG DC-DC switching regulator is a highly versatile, and efficient device that can provide clean power delivery with high power efficiency over a large input voltage and output voltage range. Its features, wide range of external components, and flexibility make it a go-to solution for many applications.
