Part Number: TPS61165 Product datasheet is taking about different values of minimum PWM dimming frequencies.
I would like to clarify, which is right and which is typo.
1. Datasheet says, min PWM freq is 5kHz in 7.2 Recommended Operating Conditions…
Part Number: TPS61165 Hey team,
What are your thoughts on the TPS61165 to drive an LCD backlight that needs a 20V supply at 60mA as well as dimming? Vin ranges from 10-17V. Is there a different part I should be suggesting? Let me know offline is there…
Part Number: TPS61165 Dear Team,
We are under developing one 5 inch TFT cluster Project,
and its backlight are 6series and 3 parallel for the backlight LED. Kindly find the attachment.
And we have enclosed also schematic diagram also, our LCD backlight…
Part Number: TPS61165 Hello Sir:
If I need to get 12V/300mA by using TPS61165.
Please let us know can we let TPS61165 keep in boost function and without dimming?
I mean just fixed output voltage at 12V and keep CTRL high level, and the schematic…
Part Number: TPS61165 Other Parts Discussed in Thread: TPS61160 , TPS61160A Hi support team,
Section 8.3.2 mentions "Open LED Protection".
If the connection with the LED is normal, but Rset, which determines the current value, is opened or shorted…
Part Number: TPS61165 Hi Team,
We are going to design a circuit with an input of 12VDC that consists of 2 LED strips running simultaneously which should have 400mA @ 12VDC individually along with PWM dimming control. For this application, we are going…
Part Number: TPS61165 Hi team, I'd like to know about the powerup sequence for CTRLpin. Is there any problem if the voltage is applied to CTRLpin before Vinpin input? And, is there any problem if I connect Vin and CTRL directly because I don't use dimming…
Hi just to provide more details on intended design :
Input voltage : 5V , Vout = 18.2V , Iled=360mA max ambient temp is 50 degC. ( LCD Backlight driving 6*6 Leds - single chain )
Is TPS61165 WSON package a good fit for this application ?
Appreciate…
Part Number: TPS61165 Hi
We would like to know how to calculate the resistance for feedback circuit.
here is the application:
Vin = 5V
Vout = 6V for 2 LEDs in serial
Iout = 350mA
Thanks.
Jack
