Product Overview

DC2779A demonstration circuit is an 8V, 16A synchronous step-down Silent Switcher® 2 with spread spectrum frequency modulation featuring the LT®8644S. The demo board is designed for 1.2V output from a 2.7V to 8V input. The LT8644S is a compact, ultralow emission, high efficiency, and high speed synchronous monolithic stepdown switching regulator. The integrated bypass capacitors optimize all 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. Peak current mode control with minimum on-time of as low as 20ns allows high step-down conversion even at high frequency. The LT8644S switching frequency can be programmed either via an external resistor or an external clock over a 300KHz to 3.5MHz range. The default frequency of demo circuit 2779A is 2MHz.
  • Demo board has an EMI filter installed
  • 1.18V to 1.22V output voltage at VIN = 5V
  • 2MHz switching frequency
  • 90.2% efficiency at VIN = 5V, VOUT = 1.2V, IOUT = 8A
