Analog Devices Inc. DC2910A Demo Board for LTM4691 µModule® Regulator
Analog Devices Inc. DC2910A Demo Board provides an evaluation and prototyping platform for the LTM4691 µModule® Regulator. The LTM4691 µModule Regulator is a complete 2A, dual-output, switching-mode DC-DC power supply in a tiny 3.0mm x 4.0mm x 1.18mm LGA package. Included in the package are the switching controller, power FETs, inductors, and all supporting components.
The DC2910A Demo Board operates by default at a fixed 2MHz and can be synchronized from 1MHz to 3MHz via the MODE/SYNC pin. With its high switching frequency and current mode architecture, fast transient response to line and load changes are possible without sacrificing stability. The DC2910A can be used in forced continuous mode or pulse skip mode for low noise, or in burst mode operation for high efficiency at light loads.
