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.
