WS9252ProductDescription

Bypass Capacitor

The bypass capacitor on VCC should be as close as

possible to the VCC pin

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 of the bulk

capacitor.

The Area of Power Loop

The area of main current loop should be as small as

possible to reduce EMI radiation, such as the primary

current loop, the snubber circuit and the secondary

rectifying loop.

FB Pin

The feedback divider should be as close as possible to

FB Pin and the node must keep away from dynamic node of

transformer.
