LMR16006Y-Q1 SIMPLE SWITCHER Buck Regulators With High-Efficiency ECO Mode

1 Features

3 Description

The LMR16006Y-Q1 is a PWM DC-DC buck (step-

down) regulator. 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 2.1 MHz

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 LMR16006Y-Q1

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 LMR16006Y-Q1 is

available in a low profile SOT-6L package (2.9 mm x

1.6 mm).
