Working Principle

The NCV890100PDR2G power regulator device is based on a high frequency synchronous buck topology, providing solutions for a wide range of supply conditions and high efficiency power solutions. The maximum efficiency of up to 92% allows the device to fully utilize the available power with minimal energy loss.

This device consists of an internal high efficiency synchronous buck topology, which works on the principle of increasing or decreasing voltage by adjusting the amount of time that the switch is on or off. This process is adjusted through the use of an external resistor and alternating between the high side and low side transistors to create a forward then reverse current flow. The voltage is then enabled by the pulse-width modulation (PWM) signal provided by a microcontroller, which is used to control the on and off times of the switch.

The device can achieve high efficiency and low dropout voltage due to a unique soft transition technology, which enables smooth switching between the high and low sides of the MOSFET switches. In addition, it features dynamic output voltage tracking, which ensures the device is always operating at the optimal voltage level.

The NCV890100PDR2G DC-DC switching regulator is an ideal solution for providing power to consumer electronics, communications, industrial and automotive applications. This device offers high efficiency and an adjustable, synchronous buck operation in a compact 4mm x 4mm package. It is suitable for a wide range of power supply applications, from providing core voltage supplies to powering logic, interface and microprocessor applications.
