The MP2354DS-LF is a highly adaptive DC-DC switching regulator that is engineered to meet the needs of an ever-growing variety of applications. It features a wide input voltage range and can be used as a buck regulator, boost regulator, or in a synchronous rectifier mode; allowing it to take advantage of the varying conditions encountered in different environments. The MP2354DS-LF also has a programmable soft-start time and current protections for overcurrent, overtemperature, and inductor overcurrent (DCSLP). It is capable of delivering up to 10A of output current with a switching frequency from 500kHz to 3.5MHz.

At the heart of the MP2354DS-LF is an input voltage range of 4.5V – 22V and is capable of adjusting its output voltage from 0.825V – 20V. It has a built in MOSFET at the internally integrated synchronous rectifier and a VREF voltage of 0.6V. With a programmable soft-start time of up to 16ms, it ensures a smooth transition when powering up or down.

The MP2354DS-LF is a two-channel device and has two individual DC/DC controllers that can be used independently or in tandem. Using both controllers independently allows for two completely isolated input and output voltages, allowing for redundancy in critical applications. The device also comes equipped with several safety features such as Over-Current Protection (OCP) and Thermal Shutdown (TSD) to protect against excessive currents and temperatures.

The MP2354DS-LF has PGOOD and SS indicators on the device, which allows for easy monitoring of the output voltage. The PGOOD indicator provides an outputs a logic HIGH when the output voltage is within regulation. The SS indicator will output a logic HIGH when the soft start is active, the output voltage is in regulation, and the switch is enabled. In addition to these indicators, the MP2354DS-LF also features an Enable function, allowing the user to turn on and off the output switch, as well as a Fault pin that will output a logic LOW when a fault occurs.

The MP2354DS-LF is a single supply device and its maximum operating temperature is 85 degrees Celsius. Its wide range of operating voltages coupled with its built-in protective functions make it an ideal DC-DC switching regulator for a variety of applications, from consumer electronics to automotive and industrial applications.

Overall, the MP2354DS-LF is a highly responsive and adaptive DC-DC switching regulator that is designed to meet the ever-changing needs of a variety of applications. Its wide input voltage range and configurable safety features make it an ideal choice for applications requiring a reliable and efficient power supply solution.
