iW3677数据手册Renesas中文资料规格书

描述 Description

The iW3677 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 iW3677 integrates a high-voltage startup device which also reduces standby power consumption during normal operation.

The iW3677 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 option without integrated high-voltage startup, see iW3671.
