Overview

TopologyPower Factor Correction
Input voltage90-265 V
Output 1390 V / 1.92 A
IC revisionAN1885.0

Description

This application note describes the design andimplementation of a 390V, 750W, Continuous ConductionMode (CCM) Boost PFC converter using either ISL6731A orISL6731B. The converter exhibits high power factor, low THDand high conversion efficiency. The ISL6731A, ISL6731B arevoltage mode power factor correction (PFC) controllersdesigned to drive cost-effective high performance convertersto meet the tight input line harmonic requirements. The IC canbe ISL6731A (124kHz) or ISL6731B (64kHz).
