Overview

Description

The iW3671 front-end flyback power factor correction device provides high power factor (PF >0.9) and low THD (<20%) down to 33% load current using Renesas' PF-Boost™ technology. The device can be configured in both isolated and non-isolated configurations, as a buck, buck-boost or flyback converter, and consumes less than 150mW no-load standby power at 230VAC

The iW3671 integrates a full range of protection features including output overvoltage, over-power, input overvoltage and undervoltage, overcurrent and sense resistor short circuit protection, open loop, and over-temperature protection.

For an integrated high-voltage startup option, see the iW3677.
