Analog Devices LTM4705 | Demoboard DC3051A

Beschreibung

Demonstration circuit 3051A features the LTM4705, a high efficiency dual 5A or single 10A μModule® DC/DC regulator in a compact and low profile 6.25mm × 7.5mm × 3.22mm BGA package. The LTM4705 can take 3.1V to 20V input and generate 0.6V to 5.5V output (stepdown only). The DC3051A demo board is designed to take 6VIN to 20VIN to dual 5A jumper selectable outputs. The board operates by default at a fixed 1MHz and can be synchronized from 1MHz to 3MHz via the MODE/SYNC pin. With its high switching frequency and current mode architecture, a fast transient response to line and load changes is possible without sacrificing stability. The DC3051A can be used in forced continuous mode or pulse-skipping mode for low noise, or in Burst Mode® operation for high efficiency at light loads. Please see the LTM4705 data sheet for more detailed information.It is recommended to read the data sheet for the LTM4705 prior to making any changes to the DC3051A.
