Input voltage90-264 V
Switching frequency0 kHz
Output 1400 V
IC revision2.0

Description

The EVL6462A-250W-M demonstration board, based on the new L6462A transition mode power factor controller, implements a 250 W wide-range input PFC pre-regulator. Thanks to the L6462A small package (SOT23-6L) and to its embedded IPs, this design offers a minimal component count, a simple and easy design, high efficiency, and very low input current distortion (THD) under all operating conditions.

Features

Universal input voltage range: 90 to 264 Vac with 47 Hz to63 Hz frequencyRegulated output voltage: 400 VdcMaximum output power: 250 WTotal Harmonic Distortion (THD): < 5% at full load and < 15% down to 20% loadPeak efficiency: 97.4%Mains harmonics: meets EN61000-3-2 Class-D and JEITA-MITI Class-DEMI: according to EN55022 Class-B

Typical applications

  • PFC pre-regulators for: LED-based lamps and luminaires
  • PFC pre-regulators for: AC-DC adapters and other EN61000-3-2 or JEITA-MITI compliant applications
