LMR36520ADDAR Description

The LMR36520ADDAR regulator is an easy-to-use, synchronous, step-down DC/DC SIMPLE SWiTCHER converter. With integrated high-side and low-side power MOSFETs, output current up to 2A is delivered over a wide input voltage range of 4.2 V to 65 V. The transient tolerance that goes up to 70 V reduces the solution size and cost to protect against overvoltages and meets the surge immunity requirements of IEC 61000-4-5. The LMR36520 uses peak-current mode control to provide optimal efficiency and output voltage accuracy. Precision enable gives fexibility 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 filtering and delay, offers a true indication of system status, eliminating the requirement for an external supervisor.
