Hello TI-Team,

Can I use the SS/TR-Pin to control the load current?

Measure the load current by adding an ext. Opamp as current-controller and feed back the signal to SS/TR-Pin to reduce the duty-cycle.

Best regards,

Hi Frank,

The SS/TR pin is used only for controlling the startup ramp of the device. As soon as the SS/TR pin voltage exceeds the reference voltage of 0.6V, the device completes the startup phase and uses an internal 0.6V reference for steady state operation. It won't be possible to control the output voltage in steady state via this pin.

Best regards,

Varun
