Part Number: TPS61165
All our CCA that uses this circuitry to drive a LCD Backlight and are working fine except a few.
The issue we have is the output is adequate for the Backlight to work but after 5-10 second after boot up the output voltage…
Part Number: TPS61165 Hi all Would you mind if we ask TPS61165? In case of Vin > Vout, concretely Vin=12V Vout=10.8V～13.6V, is it possible to use with this condtion? We assume that Vin must be Vout > Vin. As long as Vin is less than Vout, it can't be…
Hi ,
Yes, For TPS61165 ans similiar devices with Easy-Scale Mode, it may trigger Easy-Scale Mode at low dimming frequency or low duty cycle. Here is a detail analysis(take TPS61165 as an example):
The first detection delay time 100us is not very…
Part Number: TPS61165 Dear team,
On of my customer is observing production faillure with TPS61165 which is going into easyscale mode, despite the fact their 0.2% @ 5kHz PWM should keep it in PWM mode.
The generated pulse is 400ns, which is way longer…
Part Number: TPS61169 Other Parts Discussed in Thread: TPS61165 Hi Team,
We co-layout TPS61169 and TPS61165 in our board.
Seems TPS61165 has better efficiency than TPS61169, is this result normal?
Also attached our schematic, please kindly advice…
Part Number: TPS61165 Hello,
We are using TPS61165 for LCD backlight driver in our product. Recently, we have notified by our customer that LCD backlight got failed in two units and they have returned the units to us. We have investigated this issue…
Part Number: TPS61165 Is there any ways to increase the soft start/ramping time for the LED on the hardware side, instead of using PWM on the software side? I want to increase the timing to around 400ms, if not, what is the maximum value it can goes?
Part Number: TPS61165 I am testing a device that requires this chip in order to drive an LED backlight. The TPS61165 has been failing during ESD testing. The failure occurs during air discharge testing. I am looking for a good way to protect this device…
Part Number: TPS61165 Hello guys.
One of my customers is evaluating TPS61165 with TI EVM and high brightness LED prepared by them.
The LED forward voltage is 5.8V at 100mA. Their input voltage to TPS61165 is 5.0V.
Their problem is that the LED lights…
