Analog Devices LT8310EFE | Demoboard DC1963A

Description

Demonstration circuit 1963A is a resonant reset forward converter featuring the LT®8310 controller.This circuit was designed to demonstrate the high level of performance, and small solution size attainable using the LT8310. It operates at a 250kHz switching frequency, and regulates a 12V, 6A output from a 36V to 72V input source, making it well suited for telecom, industrial, andother applications. Table 1 summarizes the performance of the DC1963A.The LT8310 is a constant-frequency forward converter controller with a low side N-channel MOSFET gate driver Output regulation is handled on the secondary side by the LT1431, which is an adjustable shunt voltage regulator providing feedback to the primary side via an opto-coupler.The DC1963A takes advantage of the LT8310’s input undervoltage and overvoltage protection to shutdown the system when the input voltage is outside of the set limits. The DC1963A also has precise overcurrent protection that allows for continuous operation under short circuitconditions. The low power dissipation under a short circuit condition ensures high reliability even during a prolonged output voltage short circuit.The LT8310 data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this quick start guide for demo circuit 1963A.
