5V, Multiphase (40A, 30A, 20A), Synchronous Step-Down Silent Switcher 2

Overview

TopologyBuck Converter
Input voltage2.25-5.5 V
Output 11.2 V / 30 A

Description

Demonstration Circuit DC2874A shows the LTC®3310S 10A, Low Voltage, Synchronous Step-Down Silent Switcher operating as a multiphase 2.0MHz, 3.3V to 1.2V buck regulator. The DC2874A has three build options to provide a two phase 20A, three phase 30A, or four phase 40A 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.
