Part Number: TPS92513 Other Parts Discussed in Thread: TPS92512 , , TPS61165 As shown in Figure 3 of SLVA419B in the application note I want to change the LED current by supplying a variable Vref via R1. Is it okay to use this method with TPS92513 / TPS92512…
Part Number: TPS92513 Other Parts Discussed in Thread: TPS92512 , I have a question about the output capacitors (Cout) of TPS92513 and TPS92512. In Typical Application and EVB, Cout is placed between the anode and cathode of the LED. When I checked it with…
Part Number: TPS92513 Hi,
Good day. Our customer is using the TPS92513 and they have an inquiry for this. Kindly refer below. ""We are the manufacturer of LED lighting .we have developed LED bulb and we have issue when do the dimming by external mosfet…
Part Number: TPS92513 Hi, we are the manufacturer of led Lighting. We have developing led bulb using tps92513 driver ic. We have a issue when applying the dimming by external mosfet circuit non linear dimming (pwm 10%-draw 80ma, 20%-120ma,30%-200ma,40…
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 Team
For the application with IADJ fixed and VIN rises from 24V to 29V,
IADJ suddenly dropped to about half the value after VIN rises to 27.9V and the VISENSE became not equal to IADJ/6.
Under what condition would VISENSE become…
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 The device will initially work but if the PWM duty cycle goes to 0 the device will no longer respond to any PWM values.
I am supplying the chip with 5V.
The output is a single LED with a current of 700mA and a forward voltage of…
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 150us …
Part Number: TPS92513 Hello,
The VIH for PDIM is listed as 1.45V max in the datasheet, but the EVM says to use a PWM high level voltage of 2V or higher. Will I be okay using a 1.8V high level voltage on PDIM?
Thanks,
Michael
