Product Overview
DC2787A demonstration circuit is a high efficiency, 4 phase, hybrid converter. It can deliver 12V/100A with the input voltage from 40V to 60V. The demo board features the LTC®7821, which uses an architecture that merges a soft switching switched-capacitor topology with a traditional step-down converter to provide superior efficiency compared to the traditional switching architectures. It offers a high efficiency/high density and cost effective solution for nonisolated intermediate bus applications in power distribution, datacom and telecom as well as emerging 48V automotive systems. External MOSFETs switch at a 400KHz fixed frequency for this demo board and can be programmed from 200KHz to 1.5MHz. The LTC7821’s powerful 1ohm N-channel MOSFET gate drivers maximize efficiency and can drive multiple MOSFETs in parallel for higher power applications.
- 97.6% typical efficiency at VIN = 48V, VOUT = 12V, IOUT = 100A
- 98% peak efficiency at VIN = 48V, VOUT = 12V
