350W CCM PFC pre-regulator demonstration board based on L4984D

EVL4984-350W

Overview

The EVL4984-350W demonstration board, based on the new L4984D continuous conduction mode PFC controller, implements a 350 W wide-range input PFC pre-conditioner. It is suitable for all SMPS from 150 W to several kWs, and is compliant with IEC61000-3-2 and JEITA-MITI standards.

Main features

Line voltage range: 90 to 265 V_ac
Minimum line frequency (fL): 47 Hz
Regulated output voltage: 400 V
Rated output power: 350 W
Maximum 2 fL output voltage ripple: 12.5 V (peak-to-peak)
Hold-up time: 20 ms (VDROP after hold-up time: 300 V)
Switching frequency: 70 kHz
Minimum efficiency: 94% (at V_in= 90 V_ac, P_out= 350 W)
PCB: single-side, 70 um, CEM-1, 112 x 114 mm
