DC2202A - LT8640EUDC Demo Board | µPower Buck Silent Switcher, 5.7V ≤ VIN ≤ 42V; Vout = 5V @ 5A
Demonstration circuit 2202A is a 42V, 5A micropower synchronous step-down Silent Switcher® with spread spectrum frequency modulation featuring the LT®8640. The demo board is designed for 5V output from a 5.7V to 42V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The LT8640 is a compact, ultralow emission, high efficiency, and high speed synchronous monolithic step-down switching regulator. The integrated power switches and inclusion of all necessary circuitry reduce the components count and solution size. Special Silent Switcher architecture minimizes EMI/EMC emissions. Selectable spread spectrum mode can further improve EMI/EMC performance. Ultralow 2.5μA quiescent current in Burst Mode® operation achieves high efficiency at very light loads. Fast minimum on-time of 40ns enables high VIN to low VOUT conversion at high frequency.
