Part Number: TPS92513 Hi,
Our issues using external shunt mosfet dimming not proper working.
Analog /pwm dimming work fine.
Help us to resolve issue.

Part Number: TPS92513 Hi team,
My customer is evaluating TPS92513. Customer found the tDELAY depends on IADJ voltage.
They are using 0.01uF for COMP. According to tDELAY calculation in the datasheet, the delay would be 250us (=0.01uF * 0.7V / 28uA…
Part Number: TPS92513 Hi Team
The datasheet of the TPS92513 mentions that the current rating is 1.5A but I couldn't find any of that description in the electrical characteristics table.
Is there a clear statement of the current rating in the datasheet…
Part Number: TPS92513 Hi,
How long does it take from enabling the device to achieving setting LED current?
Though I tried simulation on Pspice for TI, it is not excused...
Conditions are followings;
VIN=24V, VOUT=20V, ILED=1A
Target time: below…
