Product Overview
EVAL-LT8643SA-AZ demonstration circuit is a 42V, 6A micropower synchronous step-down second generation Silent Switcher® with spread spectrum frequency modulation featuring the LT8643SA. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The LT8643SA is a compact, ultra-low emission, high efficiency, and high speed synchronous monolithic step-down switching regulator. The integrated bypass capacitors optimize all the fast current loops and make it easier to minimize EMI/EMC emissions by reducing layout sensitivity. Selectable spread spectrum mode can further improve EMI/EMC performance. Ultra-low quiescent current in Burst Mode® operation achieves high efficiency at very light loads. Fast minimum on-time of 30ns enables high VIN to low VOUT conversion at high frequency.
- Demo board is designed for 5V output from a 5.8V to 42V input
- Maximum output current iout is 6A (min) at TA = 25°C
- Switching frequency range from 1.85 to 2.15MHz at TA = 25°C
- 94.3% typ efficiency at VIN = 12V, IOUT = 3A, TA = 25°C
