        The LMR36015-Q1 regulator is an easy-to-use, synchronous, step-down DC/DCconverter. With integrated high-side and low-side power MOSFETs, up to1.5 A of outputcurrent is delivered over a wide input voltage range of 4.2 V to60V. Tolerance goes up to 66 V.

        The LMR36015-Q1 uses peak-current-mode control to provide optimal efficiencyand output voltage accuracy. Advanced high speed circuitry allowsthe LMR36015-Q1 to regulatefrom an input of 20 V to an output of 5 V at a fixed frequency of 2.1 MHz. Precision enable gives flexibility by enabling a direct connection to the wide input voltageor precise control over device start-up and shutdown. The power-good flag, with built-in filteringand delay, offers a true indication of system status eliminating the requirement for an externalsupervisor.

        The LMR36015-Q1 is in a HotRod™ package whichenables low EMI, higher efficiency, and the smallest package to dieratio. The device requires few external components and has a pinout designed for simple PCBlayout. The small solution size and feature set of the LMR36015-Q1 are designed tosimplify implementation for a wide range of end equipment.
