说明
-
DC414B, Demonstration Circuit is a step-up (Boost) DC-DC converter featuring the LTC1871 controller. The circuit is capable of providing an output voltage of 5V at 7A (10A peak) from an input supply of 3.3V. External frequency synchronization is provided, as are two modes of operation at light load conditions: Burst mode operation to reduce switching losses and maintain high operating efficiency and continuous mode to provide constant operating frequency with low quiescent current. The LTC1871 is a No RSENSE current mode step-up controller. It eliminates the need for a current sense resistor and maximizes the efficiency of the demo circuit - up to 95%. Applications include telecom power supplies, cellular phones, PDAs and portable electronic equipment
