3 Description
The LMR664x0-Q1 is a small 36-V, 3-A (available in
2-A and 1-A variants) synchronous step-down DC/DC
converter 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 LMR664x0-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
design 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
LMR664x0-Q1 is designed to simplify implementation
for a wide range of automotive end equipment.
