DC2822A

DC2822A is a LT8618 high efficiency 65V, 100mA synchronous buck regulator demonstration board. Demonstration circuit 2822A features the LT®8618, a high efficiency 65V, 100mA synchronous step-down regulator. The DC2822A demo board is designed for 100mA at 5V output from a 5.5V to 60V input with switching frequency of 2MHz. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The LT8618 is a high efficiency and high frequency synchronous monolithic step-down switching regulator in a 3mm × 2mm DFN package with exposed pads for low thermal resistance. The regulator’s ultra-low 2.5μA quiescent current with the output in full regulation enables applications requiring highest efficiency at very light load currents, such as automotive and battery powered portable instruments.

• Input supply range with EMI filter 5.5V to 60V
• Output voltage range 4.85V to 5.15V
• Efficiency of 90.5% at VIN = 12V, IOUT = 100mA, TA = 25°C
