MP2467DN-LF is a DC-DC switching regulator suitable for a wide range of applications. It is designed for use in buck, boost and hybrid DC-DC conversion systems. It operates from a 3.0V to 12V input voltage range and provides an adjustable output voltage up to 10V. The integrated switching synchronous rectifier and low RDS(on) MOSFETs provide high efficiency and fast transient response. The MP2467DN-LF also features programmable operations such as soft-start, output voltage tracking, and short circuit protection.

Internals of the MP2467DN-LF

The MP2467DN-LF is equipped with a high-performance voltage regulator that provides accuracy, flexibility and efficiency. The internal buck regulation loop consists of a power supply monitor (PSM), an output voltage track loop,soft start circuit and an over temperature protection circuit. The internal PSM monitors the input voltage to ensure the desired voltage level is maintained. The PSM can also be configured to adapt the output voltage dynamically to changes in the input voltage. The output voltage track loop compensates for changes in the output voltage due to load and line variations. The output voltage is adjustable between 0.8V and10V. The integrated soft-start circuit prevents large inrush currents while the chip is turning on.

integrating a synchronous rectifier and low RDS(on)MOSFETs, theMP2467DN-LF offers high efficiency and fast transient response. The synchronous rectifier improves efficiency by replacing diode rectificationwith low-RDS(on) MOSFETs. The synchronous rectifier is also capable of operating at high frequencies, which reduces power losses and component count. The low RDS(on) MOSFETs reduce switching losses and enable the chip to operate at higher frequencies for higher efficiency.

The MP2467DN-LF can be used in a variety of applications, such as:

• Portable computing systems
• Notebooks and tablets
• Camera and video-on-demand systems
• Vehicle electronics
• Home and industrial lighting

Working Principle of MP2467DN-LF

MP2467DN-LF is a DC-DC switching regulator that uses a Buck-Boost converter architecture. The control circuit inside the chip regulates the output voltage by adjusting the duty cycle of the internal MOSFETs. The output voltage is monitored by the internal regulation loop, and the duty cycle is adjusted accordingly to maintain the desired output voltage. The switching frequency can be adjusted from 500kHz to 3MHz via an external resistor.

The output of the MP2467DN-LF is filtered using an LC filter to reduce noise and maintain the output voltage stable. An internal programmable soft-start circuit prevents the chip from drawing large inrush current when the chip is powered up. The integrated short-circuit protection prevents the chip from being damaged due to excessive load. The MP2467DN-LF also has a current limit protection and thermal shutdown protection to protect the chip from being damaged in the event of a fault.

The MP2467DN-LF is an ideal solution for a wide range of DC-DC conversion applications. It provides high efficiency, fast transient response, and excellent output voltage accuracy. With the integrated synchronous rectifier and low RDS(on) MOSFETs, the MP2467DN-LF offers excellent efficiency and high switching frequencies.
