Part Number: TPS61042 Hello, I am planning to use TPS61042 as backlight source (what a surprise :) But even circuit is simple, I have problem to get the chip to work. This is schematic:
It is a part of adapter to some demo-kit. At this point I have…
Part Number: TPS61042 Hello,
I am using the TPS61042 at 33mA LED current (RSET=7.5 ohms).
Below are the switching waveforms I have captured vs the waveforms from the datasheet:
2.7V ip; 100% PWM duty cycle:
2.7V ip; 50% PWM duty cycle:
5…
Part Number: TPS61042 Hello,
I am using the TPS61042 in the below configuration:
I have tied the EN pin and PWM pin to VIN (5.5V). My LEDs work at full brightness.
When I connect the PWM pin to a PWM signal of 50kHz with 50% duty cycle, my IC…
Part Number: TPS61042 Other Parts Discussed in Thread: LM5166 , TPS62160 Hi Team,
We are using TPS61042 for driving the backlight of an LCD display.
The input of TPS61042 is fed from a 12V to 3.3V LDO, while turning on the circuit the LDO is getting…
Part Number: TPS61042 Other Parts Discussed in Thread: TPS62160 , Dear Team,
I'm using TPS61042DRBR in one of the board to power up a display backlight.
This is fed from a buck regulator TPS62160. This buck is powered from 12VDC rail, the buck is…
Part Number: TPS61042 Tool/software: I have used the part number TPS61042DRBR. attached schematic. This LED driver is not working properly, after 1 to 2 sec, display getting blank.
Please guide any hardware level settings required to drive 7inch LCD…
Part Number: TPS61042 I am trying to simulate the application circuit for the LED driver using 'PSpice for TI' but the spice model is not available. I need to simulate the exact behavious so i cannot model it myself.
Can I get the spice model for the…
Part Number: TPS61042 Tool/software: Hi team,
There are two drawings: DRB0008B and DRB0008A. The customers know that only the DRB0008B will be shipped in the future. However, they need to know the latest status and the cutoff date. Thanks!

Part Number: TPS61042 Tool/software: Hi TI,
I note that TPS61042 have two package, DRB0008A and DRB0008B. This two have a little different. But I didn`t find two kinds of full part number.
Would you like tell me this two different package full part…
Part Number: TPS61042 Hello,
I've designed a device using the TPS61042DRBR, and did the layout with the DRB0008A footprint, as we habe it in our library for other TI ICs . I didn't notice that there are 2 different footprints in the datasheet, the DRB0008A…
