Part Number: TPS61500EVM-369 Other Parts Discussed in Thread: TPS61500 Hi team,
I'm currently trying out TSP61500-EVM to power up a 7" display backlight. The display is specified to draw ~150mA@19.2V:
I'm using parallel Li-Ion batteries to power…
Other Parts Discussed in Thread: TPS61500 The efficiency of the demo board isn't what I would expect. At 6V in it draws 1.5A and the LED current is only 0.5A. Everything seems to be working, output voltages, over-voltage etc. The waveform at TP1 is…
Hi Vamsi,
What I get from the spec is that you need to driver totally 290mA current (or 4 paralleling LED strings for totally 290*4= 1160mA?) and boost the voltage to VIN+19.2V, right? The inductor value could be referred to datasheet table 4. Normally…
Other Parts Discussed in Thread: TPS61500EVM-369 , TPS61500
In slvu261 (the TPS61500EVM-369 user's guide) it indicates a
circuit that can be populated to implement PWM dimming; does this provide pure
PWM dimming by applying a PWM signal…
Hi Sean,
Thank you very much and I have one more request, can you provide the altium design files for the TPS61500EVM-369 board that would be very helpful
HI Sudheendra,
Here are some suggestions for you:
1. It since that the device doesn't work properly, I suggest you increase the OVP setting to a higher value(18V) and test again;
2. Change the compensation capacitor C4 to 220nF or 47nF and test…
Hi Tajbid,
I just used the TPS61500EVM and you can request the EVM from this website:
http://www.ti.com/tool/TPS61500EVM-369?keyMatch=tps61500&tisearch=Search-EN-Everything
And I have removed the C7 and changed the C6 from 0.1uF to 47nF. Then…
Other Parts Discussed in Thread: TPS61500 , TPS61500EVM-369 Hi,
I am trying to use the TPS61500 IC to drive a single 30W led. The led forward voltage is about 12 -13 V and i wish to have maximum possible (>2A) led current. I have built the circuit of TPS61500EVM…
Other Parts Discussed in Thread: TPS61500 , TPS61500EVM-369 So,
I'm using a tps61500 to drive a string of 1.5A LEDs in serial, I've
implemented a similar circuit using the TPS61500EVM-369 using the
supplied LEDs and a 3v power supply and 3v MCU to…
