3 Description

The LMQ664x0-Q1 is the industry smallest 36-V, 3-A

(available in 2-A and 1-A variants) synchronous stepdown

DC/DC converter with an integrated bypass and

bootstrap capacitor in an enhanced HotRod? QFN

package. This easy-to-use converter supports a wide

input voltage range of 2.7 V to 36 V (after start-up or

after operating) with transients up to 42 V.

The LMQ664x0-Q1 is specifically designed to

meet low standby power requirements for alwayson,

automotive applications. Auto mode enables

frequency foldback when operating at light loads,

allowing an unloaded typical current consumption of

1.5 μA at 13.5 VIN and high light load efficiency. A

seamless transition between PWM and PFM modes

along with very low MOSFET ON resistances makes

sure there is exceptional efficiency across the entire

load range. The control architecture (peak current

mode) and feature set are optimized for an ultrasmall

solution size with minimal output capacitance.

The device minimizes input filter size by using

dual-random spread spectrum (DRSS), a low-EMI

enhanced HotRod? QFN package, and an optimized

pin-out. The MODE/SYNC pin can be used to set or

synchronize the frequency to avoid noise sensitive

frequency bands. There are NC pins between critical

high voltage pins, reducing potential failures (optimal

pin FMEA). The rich feature set of the LMQ664x0-

Q1 is designed to simplify implementation for a wide

range of automotive end equipment.
