The LT8312 is a power factor correction (PFC) boost controller. A LT8312-based design can achieve a power factor of greater than 0.99 by actively modulating the input current, allowing compliance with most Harmonic Current Emission requirements.

The LT8312 is well suited for a wide variety of off-line applications. The input range can be scaled up or down, depending mainly on the choice of external components. Efficiencies higher than 95% can be achieved with output power levels up to 250W.

Product Detail

Demonstration Circuit 2104A is an off-line boundary conduction mode power factor correction (PFC) boost converter featuring the LT8312. 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.
