NCP1835BMNR2G, a High-Efficiency, Low-Cost, Wide-Input-Voltage PWM Buck Switching Voltage Regulator, is a new generation high-efficiency voltage regulator produced by ON Semiconductor. It is a highly integrated device that integrates all the necessary components to regulate the opposite current of an associated battery charger circuit. This device functions as an active current source because of its variable switching frequency.

Application Field

The NCP1835BMNR2G is designed to provide a regulated output voltage, adjustable up to 5.5V with a minimum voltage difference between the battery voltage and the output voltage of only 0.8V. It is mainly used to provide power supply for charging and discharge processes of the battery. This device is perfect for a wide range of applications, such as geoelectric self-balancing vehicles, balance vehicle charging, telecom power supply, UPS power supply, and so on.

Working Principle

NCP1835BMNR2G is a step-down type switching voltage regulator, it works with the principle of switching power supply, that is, the electrical energy is converted from AC to DC when passing through a rectifier circuit without any transformer, and then it is converted back to AC through a high-frequency inverter circuit. The switching state of the rectifier and inverter circuit is controlled by the PWM pulse to realize the output voltage control. In addition, the device has a maximum of 95% conversion efficiency. Its low quiescent current consumption and low power consumption makes give it high performance.

This device integrates several useful features, including protection functions such as thermal shutdown, undervoltage protection, disabled output, and overcurrent protection. In addition, the device also has self-balancing features, such as battery type selection, and termination voltage regulation, making it suitable for a variety of battery types. Finally, the device also has high-precision accuracy and wide temperature range, which make it perfect for applications with high performance demands.

In conclusion, the NCP1835BMNR2G is an ideal choice for power management components to power the battery charger in the battery charging process. It provides low power consumption, high conversion efficiency, good accuracy and protection functions, making it perfect for various battery charging applications.
