Hi Sir,

Pls kindly advise,

What is OCP current threshold of TLV62565?

Thanks, Ian.

    Hi Ian,

    TLV62565 uses the valley current limit, where the inductor current is monitored during Toff using the low-side FET. When the inductor current is above the low-side FET peak current limit (ILIM, LS), the off-time will increase until the low-side current is equaled to ILIM, LS (1.7A, typical). To prevent inductor saturation, the device has an additional high-side FET peak current limit (2.0A, typical). When the ILIM,HS is reached, the high-side FET is immediately turn-off.

    For detailed explanation on valley current limit operation, please check the link below.

    Understanding valley current limit
    The concept of current limit seems pretty straightforward: when you increase the output current of a DC/DC converter, at a certain point it’s not possible to increase it any further. This level is the…
