Application Field and Working Principle

The LM25017SD/NOPB is ideal for applications requiring efficient power conversion, such as notebook computers, USB-powered devices, LCD TVs, and PDAs. It can provide up to 2A peak output current for an input voltage range of 4.5V to 15V. As a synchronous buck regulator, the LM25017SD/NOPB is designed to regulate a voltage from the input to the output. It uses high-frequency switching technology to achieve high power efficiency.

It is made up of three major parts, the rectifier, the switcher, and the controller. The rectifier rectifies the input voltage and provides the energy to the switch. The switch then regulates the voltage output depending on a control signal from the controller. The controller controls the switching frequency and the output voltage.

The LM25017SD/NOPB features a fixed frequency of 400 kHz, an input voltage range from 4.5V to 15V, output voltages up to 5.5V and a logic input supply down to 1.62V. It has a high power conversion efficiency of up to 97% and features an open loop output voltage compensation, a soft-start with adjustable current limit, an integrated over-temperature protection with Hibernate mode, and an external output discharge circuit.

Overall, the LM25017SD/NOPB from Texas Instruments is a high performance synchronous buck regulator controller that is ideally suited for applications requiring efficient power conversion.
