Analog Devices LT8312 | Demoboard DC2104A

Description

Demonstration Circuit 2104A is an off-line boundary conduction mode power factor correction (PFC) boost converter featuring the LT®8312. Boundary conduction mode offers inherent MOSFET valley switching to reduce the switching loss and the boost diode zero current switching to remove the diode reverse-recovery loss. The demo board provides a 400V/150W single constant-voltage output suitable for applications requiring regulated input voltage.

The DC2104A is optimized to operate over a wide AC input voltage range (90VAC to 265VAC, 47Hz to 63Hz). Output voltage accuracy stays within ±5% over the whole input voltage and load range. It provides a high power factor (>0.95) enabling the design to be used worldwide. It is also designed to comply with the IEC61000-3-2 Class-D harmonics standard and the EN55022 conducted EMI standard.

This DC 2104A evaluation board uses a two-layer printed circuit board (PCB) designed for 150W (400V/0.375A) rated power. It can also be changed for other power level applications. Please refer to the Typical Applications sectio in the data sheet for more information.

The LT8312 is available in a low profile, thermally enhanced 16-lead MSOP package.

The LT8312 data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this demo manual.
