Currently using default current setting & enable pin permanent high
in case i would like to change Configuration Parameters through I2C, do i need to toggle enable pin or genrate reset condition?
let me know, if below…
Part Number: TPS61177A Other Parts Discussed in Thread: TPS61196 Hello guys,
One of my customers is looking for a boost multi channel constant current output LED driver which can program the outputs current or PWM ratio individually. I thought TPS61177A…
Part Number: TPS61177A HI
i am using tps61177a and trying to check the registers using i2c where i receive NACK after sending the slave address,
my hardware follows like this as in pin order
1 - pull up of 4.7k ohm connected to data pin of microccontroller…
Part Number: TPS61177A Hi,
I have created a small prototype board using the TPS61177A which powers an array of LEDs as expected. I now want to be able to alter some of the parameters via I2C, but keep getting a NACK response as shown below. I have configured…

Part Number: TPS61177A 1. Can we use this device with PWM control only? as my board do not have interface available for I2C
2. will it be suitable for 9 LED strings with 3 LED's in serial (max IF 20mA, VF 3.2V for each LED), so combining all CS1 to…
Part Number: TPS61177A I have a design with TPS61177a, following the reference design.
there's another device on i2C bus with address '5d'.
after asserting the 'ENB' pin, I can find two devices on I2C line with address '2C' and '5d'.
the address…
