DC2841A

Demonstration circuit 2841A is a 42V, 15A synchronous step-down Silent Switcher 2 with spread spectrum frequency modulation featuring the LT8648S. The 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 LT8648S is a compact, ultralow emission, high efficiency and high speed synchronous monolithic stepdown switching regulator. The integrated bypass capacitors optimize the fast current loops and make it easier to minimize EMI emissions by reducing layout sensitivity. Selectable spread spectrum mode further improves EMI performance, making it perfect solution to the noise sensitive applications.

• Switching frequency of 400KHz(typ) at TA = 25°C
• Efficiency of 96.5% at TA = 25°C, VIN = 12V, VOUT = 5V, IOUT = 9A
