Analog Devices LTM8055 | Demoboard DC2017A

Beschreibung

Demonstration circuit 2017A features the LTM®8055, a buck-boost μModule® regulator that accepts input voltages lower, higher or the same as the output, but is also highly efficient due to its four-switch architecture. The output for DC2017A is 12V and the input voltage range is 5V to 36V. The maximum output current is 6A and the switching frequency is 600kHz.DC2017A supports the adjustable and controllable features of the LTM8055 including output voltage and current regulation, switching frequency, RUN threshold, soft-start period, synchronization and reverse inductor current inhibit. In most cases, adjustment is made by modifying the appropriate resistor or capacitor component(s). DC2017A provides output current monitoring and a clock output.Input current monitoring and regulation requires the installation of a current sense resistor. The SVIN input for controller power can be made a diode-OR of power VIN and the output voltage to extend the operating range of power VIN to lower voltages. There are places to mount optional components that add an LC input filter and also a unity gain buffer to operate multiple DC2017As in parallel.The LTM8055 data sheet must be read in conjunction with this demo manual to properly use or modify DC2017A.
