Hello E2E,

I seted the Vadj to 0-V(GND) for stop the ILED completely. However LEDs are lighting.
Please let me know how to stop the ILED. (without shunt-FET using)

Hello ACGUY,

The TPS92515 has a minimum on-time, after every off-time it will turn the MOSFET on for a minimum on-time. To turn off the LEDS either a small load needs to be added or the TPS92515 needs to be disabled.

Best Regards,
