MP2420 75V, 0.3A Synchronous Step-Down Converter with Watchdog The Future of Analog IC Technology DESCRIPTION FEATURES The MP2420 is a step-down switching regulator 20 A Quiescent Current for Buck Only with integrated high- and low-side, high-voltage Wide 4.5V to 75V Operating Input Range power MOSFETs. It achieves a highly efficient (80V ABS MAX) output of up to 0.3A, and the integrated 1.2 /0.45 Internal Power MOSFETs watchdog adds additional security redundancy Programmable Soft Start to the system. FB Tolerance: 1% at Room Temperature, 2% at Full Temperature The wide 4.5V to 75V input range accommodates Adjustable Output Voltage a variety of step-down applications in an Integrated Window Watchdog automotive environment. A 5 A shutdown mode quiescent current in a full temperature Power-On Reset during Power Up and range is ideal for battery-powered applications. Under-Voltage Lockout (UVLO) Programmable Short Window Mode or Long The MP2420 allows for high-power conversion Window Mode efficiency over a wide load range by scaling Low Shutdown Mode Current of 5 A down the switching frequency under light-load Available in a TSSOP-16 EP Package conditions to reduce switching and gate driver losses. The start-up switching frequency and APPLICATIONS short circuit can also be scaled down to prevent Automotive Systems an inductor current runaway. Industrial Power Systems Full protection features include under-voltage Distributed Power Systems lockout (UVLO) and thermal shutdown. Thermal Battery-Powered Systems shutdown provides reliable, fault-tolerant All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. operation.
