MV1012SC

6.3 Abnormal heat buildup

The MV1012SC doesn’t incorporate thermal shutdown. Install a separate protection circuit, if necessary.

6.4 CS pin open-circuit

If the CS pin open-circuit occurs, Vcs will increase due to the internal pull-up current and remain above the CS pin

reference voltage. The IC will therefore operate with the minimum on-time Ton_min, and Io will decrease.

6.5 CS-GND short-circuit

The IC will be unable to perform peak current detection at the CS pin and will operate with the maximum on-time

Ton_max. As Io increases, install a separate protection circuit, if necessary.

6.6 Current detection resistor open-circuit

The source of MOSFET will float, and MOSFET operations will become unstable. If the MOSFET switches off, Io will

approach zero. However, if the MOSFET is on, overvoltage will be applied to a CS pin, resulting in potential damage to the

IC. Install a separate protection circuit, if necessary.

6.7 Current detection resistor short-circuit

Vcs will become nearly equal to GND, and the IC will operate with the maximum on-time Ton_max. As Io increases,

install a separate protection circuit, if necessary.
