Description
- DC2874A-C, Demonstration Circuit shows the LTC3310S 10A, Low Voltage, Synchronous Step-Down Silent Switcher operating as a multiphase 2.0MHz 3.3V to 1.2V buck regulator. The DC2874A provides a two phase 20A output solution. The LTC3310S supports adjustable output voltages from 0.5V to VIN and operating frequencies from 500kHz up to 2.25MHz in multiphase operation. DC2874A operates in pulse skip mode and allows the slave phases to stop switching first before the master starts skipping pulses for better low current efficiency
