DC2535A

Demonstration circuit 2535A is a 42V, dual channel, 2A synchronous step-down regulator featuring the LT®8653S. The LT8653S is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator which features the second generation Silent Switcher® technology that minimizes EMI and reduces PCB layout sensitivity. The demo board is designed for two outputs: 5V and 3.3V from a 5.5V to 42V input. Each output can source up to 2A continuous current at the same time. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. Selectable spread spectrum mode of operation can further improve EMI/EMC performance. Ultralow quiescent current in Burst Mode® operation achieves high efficiency at very light loads.

• Switching frequency of 2MHz(typ) at TA = 25°C
• Efficiency of 93.1% at TA = 25°C, VIN = 12V, IOUT1 = 1A, IOUT2 = 1A
