DC2242A

DC2242A is a demonstration circuit featuring LT®8494 a monolithic SEPIC converter. The demo board is designed for 5V output from a 3V to 60V input at 450KHz switching frequency. The max output current is 1A when the input voltage is above 12V, and is reduced with lower input voltage. The quiescent current of LT8494 is less than 7μA when operating. Dual supply pins (VIN and BIAS) allow the part to automatically operate from the most efficient supply. Low ripple Burst Mode® operation increases the efficiency at the light load while keeping the output ripple below 10mV.

• Efficiency at DC is 80.3% typ at VIN = 12V, IOUT = 1A
