Analog Devices LTM4652 Demo Board (DC3230A)

     Analog Devices LTM4652 Demo Board (DC3230A) is the evaluation and development platform for the LTM4652µModule Regulator. The LTM4652 is a bi-directional, dual-output, non-isolated switching mode DC-DC power supply with a total DC output error of ±1.5% over line, load, and temperature variations.

     The LTM4652 can provide two ±25A outputs or one ±50A output with only a small number of external input and output capacitors and setup components. The device provides precisely regulated output voltages that can be programmed with external resistors from 0.6V(DC) to 7.5V(DC) over input voltages from 4.5V to 18V.

     Analog Devices LTM4652 Demo Board can be configured as a source or sink for output load current. The demonstration circuit is optimized for +9V(IN) and -5V(OUT) conditions using the default frequency of 780kHz. The current mode architecture used in the LTM4652 is peak current mode control. This section works in continuous current mode by default, but can be placed in pulse skip mode to optimize efficiency under light load.
