DC2104A - LT8312EMS Demo Board | Boost Controller with PFC, 90VAC ≤ VIN ≤ 265VAC; VOUT = 400Vdc @ 0.375A

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.
