DC2629A

DC2629A demonstration circuit features the LTC®3310S 10A, low voltage, synchronous Step-Down Silent Switcher® 2 operating as a 2MHz 3.3V to 1.2V, 10A buck regulator. The LTC3310S supports output voltages from 0.5V to VIN with operating frequencies from 500KHz up to 5MHz. The LTC3310S is a compact, ultralow emission, high efficiency, and high speed synchronous monolithic step-down switching regulator. The integrated bypass capacitors optimize all the fast current loops and make it easier to minimize EMI/EMC emissions by reducing layout sensitivity. Fast minimum on-time of 35ns enables high VIN to low VOUT conversion at high frequency.

• 2.25 to 5.5V DC2629A input voltage range
• Switching frequency range from 1.8Mz to 2.2MHz
• 91% typ efficiency at VIN = 3.3V, IOUT = 5A
