The LM684x0-Q1 are a family of 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 36V (42V tolerant) The LM684x0-Q1 is dual phase capable by simply connecting the compensated error signal between the primary and secondary device. The LM684x0-Q1 comes with pin selectable fixed output voltages of 3.3V and 5V or in adjustable configuration. The low EMI operation is enabled with minimized loop inductance and optimized switch node slew rate. A pin-selectable ±5% or ±10% dual-random spread spectrum (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 a 30ns typical minimum on-time allows high conversion ratios at high frequencies coupled with a fast transient response and excellent load and line regulation.

The LM684x0-Q1 buck converters are specifically intended for functional safety relevant applications. An array of safety features including ABIST at start-up, redundant and fast VOUT monitoring, feedback path failure detection, redundant temperature sensor, thermal shutdown, and current limiting significantly reduce the residual failure-in-time (FIT).
