TPS561201: What will happen if Boost capacitor (0.1uf) not mount.

Satish Ghariya

Part Number: TPS561201

Hi,

I want to know exact behavior of IC if Boost capacitor (0.1uf) not mount (pin 6).

1. Is IC can damage ? (What will happen to upper and lower internal MOSFET in IC)

2. What could be the other possibility, like if I power on again after mounting (Assume earlier it was not mounted and one time power ON /OFF is already done)

Thanks,
Satish

Hi Satish,

From my experience, there will be no damage to IC. The device will still switching but the boot voltage will be low. There will be a big voltage drop on the FETs.
