3 Description
The LM656x0-Q1 are a family of stackable,
automotive buck converters designed for high
efficiency, high power density, and ultra-low
electromagnetic interference (EMI). The converters
operate over a wide input voltage range of 3V to 70V
simplifying input surge protection design.
The low EMI operation is enabled with minimized loop
inductance, pin-selectable SW node slew-rate control
and dual-random spread spectrum (DRSS). The
DRSS significantly reduces peak emissions through
a combination of triangular and pseudo-random
modulation while keeping output voltage ripple very
low.
The current-mode control architecture with 36ns
minimum on-time allows high conversion ratios at high
frequencies, easy loop compensation, fast transient
response, and excellent load and line regulation. Up
to two converters can be set up in an interleaved
mode (paralleled outputs) with accurate current
sharing for supporting output current up to 16A.
