Introduction

The MP38892DN-LF is a DC/DC switching regulator designed to provide a regulated output performance while delivering high-efficiency control of the input-to-output current. This device provides synchronous rectification, power factor control, 3-phase or single-phase synchronous buck, or buck-boost operation. The MP38892DN-LF also features programmable current limit, adjustable peak current limit and adjustable voltage lockout. With the ability to deliver up to 1.2A of output current, the MP38892DN-LF provides an ideal solution for applications requiring low-voltage and high-current operation.

Application Field

The MP38892DN-LF is an easy-to-use, yet powerful and accurate solution for controlling the input-to-output current in a variety of applications including low-voltage lighting and display designs, notebook PCs, and other battery-powered systems. Additionally, the MP38892DN-LF can be used in medical and industrial process control applications, as well as digital set-top boxes and other consumer electronics designs where high power supply efficiency is required.

Working Principle

The MP38892DN-LF uses a three-phase operation to generate an accurate output voltage. A voltage divider is used to set the output voltage to the desired level, while a pair of MOSFETs are turned on and off in a coordinated pattern to shape the input-to-output current waveform. This waveform is monitored by the internal current sense amplifier, which adjusts the RDS(ON) of the MOSFETs to maintain the desired output current. In addition, the built-in peak current limiting circuit helps to protect against current overloads.The MP38892DN-LF also features a programmable current limit feature. This feature allows the user to set the maximum current that can be drawn from the output. When the current limit is exceeded, the device will shut down to prevent excessive power dissipation. Additionally, the MP38892DN-LF has adjustable voltage lockout. This feature allows the user to set the minimum voltage at which the device will stay on. This ensures that higher-priority circuits are not interfered with by an excess of power on the output.

Conclusion

The MP38892DN-LF is an ideal solution for applications requiring low-voltage and high-current operation. It is designed to provide a regulated output performance while delivering high-efficiency control of the input-to-output current, and features synchronous rectification, power factor control, programmable current limit, adjustable peak current limit, and adjustable voltage lockout. With these features and its wide range of applications, the MP38892DN-LF is an excellent choice for designers looking for an easy-to-use, yet powerful and accurate DC/DC switching regulator.
