3 Description

The LMR36006-Q1 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 is delivered over a wide

input voltage range of 4.2 V to 60 V. Tolerance goes

up to 66 V.

The LMR36006-Q1 uses peak-current-mode control

to provide optimal efficiency and output voltage

accuracy. Advanced high speed circuitry allows the

LMR36006-Q1 to regulate from 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 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.

The LMR36006-Q1 is in a HotRod? package which

enables low EMI, higher efficiency, and the smallest

package to die ratio. 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-Q1 are designed to simplify

implementation for a wide range of end equipment.
