DC1939A

DC1939A is a demonstration circuit featuring the LTM®8052A. This is a 36V, 5A, 2-quadrant CVCC step-down μModule® regulator. The demo circuit is designed for a 2.5V output from an input voltage range of 6V to 36V. The output can source 5A or sink 5A. The circuit can be operated in either constant voltage mode or constant current mode. When the output sinks current, the circuit maintains its output voltage regulation by power conversion, not power dissipation. This means that the energy provided to LTM8052A is in turn delivered to its input power bus. There must be something on the input power bus to accept or use the energy.

• 2.5V ±5% output voltage at IOUT = 5A to -5A
• 450KHz switching frequency
• ±5A maximum output current
• 84% typical full-load efficiency at VIN = 12V, IOUT = 5A
