DC2560A

DC2560A demonstration circuit is a 18V, 10A synchronous step-down Silent Switcher®2 with spread spectrum frequency modulation featuring the LT®8642S. The demo board is designed for 1.2V output from a 2.8V to 18V input. The LT8642S is a compact, ultralow 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. Fast minimum on-time of 20ns enables high VIN to low VOUT conversion at high frequency.
