240W All-in-One PC Power Supply Evaluation Board

Overview

TopologyPower Factor Correction
Input voltage110-230 V
Switching frequency26 kHz
Output 112 V / 20 A

Description

The NCP1615AIOGEVB Evaluation Board is a high voltage PFC controller designed to drive PFC boost stages based on an innovative Current Controlled Frequency Foldback (CCFF) method. In this mode, the circuit classically operates in critical conduction mode (CrM) when the inductor current exceeds a programmable value. When the current is below this preset level, the NCP1615AIOGEVB Evaluation Board linearly decays the frequency down to a minimum of about 26 kHz when the input current is zero. CCFF maximizes the efficiency at both nominal and light load. In particular, the standby losses are reduced to a minimum. An innovative circuitry allows near-unity power factor even when the switching frequency is reduced.
