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.
