The MP2498DV-LF-Z is a current-mode DC-DC synchronous buck converter with an integrated high-side and low-side MOSFET driver. This device is part of a family of products by Monolithic Power Systems designed for fairly high power applications up to 2A of continuous output current. This device is suitable for applications such as industrial, consumer, computing, and automotive.

The MP2498DV-LF-Z features a synchronous buck topology which makes it one of the most efficient, cost effective and simplest of the DC-DC buck regulators. The device integrates a low-side MOSFET and a high-side MOSFET into a synchronous buck converter, with an integrated high-side and low-side MOSFET driver. The integrated high-side and low-side driver design eliminates the need for an external gate driver. The synchronous rectification technique significantly reduces switching losses compared with traditional PWM converters. This results in an efficiency up to 90% without any external components and up to 95% with optimal component choice.

The Monolithic Power Systems MP2498DV-LF-Z is a highly efficient, monolithic synchronous buck converter that operates from 6V-60V input and regulates a 0.9V-50V output. It utilizes an adaptive on-time control architecture to keep the output within a ±2% accuracy from no-load to full-load. The device has a wide output current range from 120mA to 2A, with a peak current of 6A and an internal compensation for easy loop tuning. The integrated high-side and low-side MOSFET drivers have a rise time of 10µs and a fall time of 8µs. The device also features over-current/over-voltage/under-voltage protection, thermal shutdown and soft-start.

The MP2498DV-LF-Z is a highly efficient, cost effective and simple solution for DC-DC synchronous buck converter applications. It is suitable for many different applications such as automotive, industrial, computing and consumer due to its high efficiency, wide input and output voltage range, and the integrated high-side and low-side MOSFET drivers. The device has a low minimum output voltage of 0.9V, an output current range from 120mA to 2A, an adjustable soft-start, over-current/over-voltage/under-voltage protection, and thermal shutdown. The integrated MOSFET driver design makes this voltage regulator the perfect choice for a wide range of applications.
