MP2562DS-LF Application Field and Working Principle:

The MP2562DS-LF is a synchronous step-down DC-DC converter module used to regulate the voltage delivered to a load. The MP2562DS-LF is an ultra-low iQ (85uA in VATR mode) and low cost power module offered in a non-isolated TO-252-3LF package. It is designed to be used in space-cocked applications for converting 5.5 VDC input to lower output voltages.The MP2562DS-LF offers excellent output efficiency and improved thermal performance. It is designed to be easy to use with integrated features such as external compensation, programmable Soft-Start, and Power Good high-side driver. The MP2562DS-LF provides high-efficiency output over a wide range of load current and qualities such as over-temperature and over-current protection for extra safety assurance.

Application Field:

The MP2562DS-LF module is primarily used in DC-DC regulated power supplies. Typical applications include battery-powered systems, automotive electronics, auxiliary power supplies, and gaming systems. The module supports voltage operating range of 5.5 to 17V, making it suitable for interfacing with most 5V and 3.3V supplies.

Working Principle:

The MP2562DS-LF operates in a fixed frequency, current-mode control architecture. The control circuitry includes a voltage feedback loop, allowing the output voltage to be regulated either using an external resistor divider, or through a direct connection to the output. The module also features progammable Soft-Start, Inrush-Current Limit, and Over-Current Protection.A voltage sense feedback allows for accurate voltage regulation along with pulse-by-pulse current limit and thermal shutdown for improved safety and reliability. Additionally, the MP2562DS-LF supports hiccup-mode for fault/overload protection, as well as integrated Power Good and Enable pins for control.

Benefits and Features:

The MP2562DS-LF module offers a number of benefits and features, including the following:• Ultra-Low Quiescent Current: 85uA in VATR mode• High Efficiency: Up to 92% • High Output Current: 4A• High Power: Up to 25W• Low minimum start up voltage: 5.5V• Programmable Soft-Start• Hiccup-Mode Over-Current Protection• Full Protection: Under-Voltage Lockout and Thermal Shutdown• Power Good output pinThe MP2562DS-LF module is an ideal choice for space-cocked DC-DC applications, offering exceptional output current and efficiency in a low-cost, low-profile package. This module is RoHS compliant and suitable for use in a wide range of applications.
