TPS27SA08-Q1: Noisy device

Part Number: TPS27SA08-Q1
Other Parts Discussed in Thread: TPS27SA08

Dear

We are using TPS27SA08 to control a heating element. The EN line is connected to PWM 1kHz, it works as expected except for the 1KhZ audible noise which is critical for our application. Any idea how to reduce noise ?

Best Regards
