Description

The LMR36006 regulator is an easy-to-use, synchronous, step-down DC/DC converter. With integrated high-side and low-side power MOSFETs, up to 0.6 A of output current can be delivered over a wide input voltage range of 60 V, with transient tolerance up to 66 V. The transient tolerance reduces the necessary design effort to protect against overvoltages and meets the surge immunity requirements of IEC 61000-4-5.

The LMR36006 employs peak-current-mode control to provide optimal efficiency and output voltage accuracy. Precision enable provides flexibility by enabling a direct connection to the wide input voltage or 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, and negates the requirement for an external supervisor.

The device requires few external components and has a pinout designed for simple PCB layout. The small solution size and feature set of the LMR36006 is designed to simplify implementation for a wide range of end equipment, including space critical applications of ultra-small field transmitters and vision sensors.
