Analog Devices Inc. LTM4652 Demonstration Board (DC3230A) is an evaluation and development platform for the LTM4652 µModule® Regulator. The LTM4652 is a bi-directional, dual-output, nonisolated switching-mode DC-DC power supply with ±1.5% total DC output error over the line, load, and temperature variations. The LTM4652 can provide two ±25A outputs or single ±50A output with few external input and output capacitors and setup components. This device offers precisely regulated output voltages programmable via external resistors from 0.6VDC to 7.5VDC over 4.5V to 18V input voltages.
The Analog Devices Inc. LTM4652 Demonstration Board can be configured to source or sink output load current. The Demonstration Circuit is optimized using a default frequency of 780kHz under the +9VIN and -5VOUT condition. The current mode architecture used in LTM4652 is peak current mode control. The part operates in continuous current mode by default but can be placed in pulse-skipping mode to optimize efficiency at light loads.
