4.2-V to 60-V, 1.5-A ultra-small synchronous step-down converter

The LMR36015 regulator is an easy-to-use,

synchronous, step-down DC/DC converter. With integrated high-side and low-side power

MOSFETs, up to 1.5 A of output current

is delivered over a wide input voltage range of 4.2 V to 60 V. Tolerance goes 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 LMR36015 uses peak-current-mode control

to provide optimal efficiency and output voltage accuracy.

Load transient performance is improved with FPWM

feature in the 1-MHz regulator. Precision enable gives 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 eliminating the requirement for an

external supervisor.
