UCC3895: CS pin reaction

Kuan Wei Chen (Kevin Chen)

Part Number: UCC3895

Dear Team,

When the CS pin larger than 2.5V trigger the protection, the circuit will latch, cycle by cycle limit, or soft start?

Besides, can I give the CS pin a DC value?

Hi, Kevin

When the CS pin larger than 2.5V trigger the protection, the controller will restart with soft start.

It is not recommended to give CS pin a DC value. Since it peak current mode, the signal on CS pin affect effective duty.
