DC3021A

DC3021A is a LTC3310S-1 3.3V to 1V at 10A, 2MHz low EMI buck regulator in a 2.11cm² solution demonstration board. Demonstration circuit 3021A shows the LTC®3310S-1 10A, 1V fixed output, synchronous step-down Silent Switcher®2 operating as a 2MHz 3.3V to 1.0V 10A buck regulator. The LTC3310S-1 supports operating frequencies from 500KHz up to 5MHz. The LTC3310S-1 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. The LTC3310S-1 has Active Voltage Positioning (AVP) where the output voltage is dependent on load current. At light loads, the output voltage is regulated above the nominal value. At full load, the output voltage is regulated below the nominal value. The DC load regulation is adjusted to improve transient performance and reduce output capacitor requirements.

• Switching frequency of 2MHz(typ) at TA = 25°C
