DC2814A-C

DC2814A-C demonstration circuit is a high-voltage, high-efficiency synchronous buck-boost DC/DC converter with an input voltage range of 26 to 80V. It can supply 2A maximum load current with an output range of 36 to 56V. The demo board features the LT8210EUJ controller. The constant frequency current mode architecture allows a phase-lockable frequency of up to 400KHz, while an optional input or output current feedback loop provides support for applications such as battery charging. With a wide input range, wide output range, and seamless transfers between operation modes, the LT8210 is ideal for industrial, automotive, medical, military, and avionics applications. The converter has four modes of operation: burst, pulse skip, forced continuous mode, or pass-thru. Pass-thru is a feature that passes the input directly to the output when the input voltage is within a user-programmable window.

• 26V to 80VIN, VOUT = 36V to 56V at 2A
• Default operating frequency of 350KHz (RT = 16.9K)
