LM656x5/LM656x5-Q1 Synchronous Buck Converters

Texas Instruments LM656x5/LM656x5-Q1 Synchronous Buck Converters are 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 65V (70V transient <100ms), reducing the need for external input surge protection. The LM656x5/LM656x5-Q1 has pin-selectable fixed output voltages of 3.3V and 5V, or in an 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 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 Texas Instruments LM656x5-Q1 devices are AEC-Q100 qualified for automotive applications.
