3 Description

The LMR16006 is a PWM DC/DC buck (step-down)

regulator. With a wide input range of 4 V to 60 V, it is

suitable for a wide range of application from industrial

to automotive for power conditioning from an

unregulated source. The regulator’s standby current

is 28 μA in ECO mode, which is suitable for battery

operating systems. An ultra low 1 μA shutdown

current can further prolong battery life. Operating

frequency is fixed at 0.7 MHz (X version) and 2.1

MHz (Y version) allowing the use of small external

components while still being able to have low output

ripple voltage. Soft-start and compensation circuits

are implemented internally, which allows the device to

be used with minimized external components. The

LMR16006 is optimized for up to 600 mA load

currents. It has a 0.765 V typical feedback voltage.

The device has built-in protection features such as

pulse by pulse current limit, thermal sensing and

shutdown due to excessive power dissipation. The

LMR16006 is available in a low profile SOT-6L

package.
