WS3410 Product Description
Over Temperature Automatic adjustment of output
current
WS3410 has over temperature regulating function, gradually
reducing the output current when the power is over
temperature, so as to control the output power and the
temperature rise, keeping the power temperature in a setting
value in order to improving the reliability of the system. The
starting regulation temperature is 135℃.
Input Filter Capacitor
In order to obtain high PF value, the input capacitor can not
be too large. 10-100nF is recommended.
Power Factor Correction
Active PFC control circuit is integrated in WS3410, which
can get high PF value and low THD.
PCB Design
The following guidelines should be followed in WS3410 PCB
layout:
Bypass Capacitor: The bypass capacitor on VCC pin should
be as close as possible to the VCC and GND pins.
Ground Path: The power ground path for current sense
should be short, and the power ground path should be
separated from small signal ground path before the negative
node of the bulk capacitor.
The Area of Power Loop: The area of power loop should be
as small as possible to reduce EMI radiation.
And the controller should be placed away from the heat
generator, such as the power diode.
