Part Number: TPS61169 Other Parts Discussed in Thread: TPS92380 Dear TI support team,
I wanted to raised a question about the TPS61169. In the datasheet, it is explain that the minimum dimming value is 1%. We are trying to design a circuit that goes further…
Part Number: TPS61169 Hi Team,
Can you help recommend several ICs for LED? Thanks.
Requirements are as follows:
1. 1.5V/1A and 18V/1A
2. Keep it as simple as possible, similar to the image below. 3. Keep the price as low as possible.
Regards, Charlie
Part Number: TPS61169 Hi,
At TPS61169 datasheet page 16, figure 18 layout, there is a rc at vin and in evm board "Using the TPS61169 Evaluation Module - User's Guide" there is a rc too in schematic at page 7.
RC filter at Vin input is…
hi Saranya
after checking, we only have Vref data available which is also shown in the datasheet 188mV-220mV, and this is valid in the temperature of 25deg-125deg.
Part Number: TPS61169 Hi Team,
May I know if there have a calculation tool for TPS61169 like the attachment?
