The LM654xx-Q1 is a buck converter family designed for high efficiency, high-power density, and low EMI performance with mitigated interference and noise technology (MINT 1) switcher technology for automotive applications. The converter operates over a wide input voltage range of 3V to 36V with pin selectable fixed output voltages of 3.3V and 5V or an adjustable output.
The low EMI operation is enabled with minimized loop inductance, optimized SW node slew-rate, and pin-selectable +8.5% or +17% 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 32ns typical minimum on-time allows high conversion ratios at high frequencies, fast transient response, and excellent load and line regulation.
