Part Number: TPS60231 HI
Is there any problem in operating the attached LED with the following circuit diagram? * LED operates at minimum 15mA * EN1=0 ,EN2=1
Part Number: TPS60231 Other Parts Discussed in Thread: LM2755 , Hi, Greetings! Our customer wants to know the ESD information (HBM/CDM/MM) for TPS60231RGTR. We checked the datasheet however it is not available there. I would appreciate if you could provide…
Part Number: TPS60231 Hello experts,
I want to drive 2 parallel LEDs (20mA/ch) like as below;
Totally I need 40mA. In this case, how do I set "ISET"?
How much Rset should set?
Thanks and best regards,
Ryo Akashi
Other Parts Discussed in Thread: TPS60231 Hi,
My customer has question about TPS60231. Could you tell me about questoin?
[Question] - If D1 is reference, how much is the current matching between D2 and D3 in the worst case? If current matching between…

(Slightly modified from original post)
Hi,
Can you please let me know whether each channel can be enabled/disabled with circuit ideas below? Each gate signals are given by CPU accordingly that enable channel…
Hi Michael,
Thank you for your support! Yes, according to customer, Vf of their LED has +/-10% variation. This could cause the current variation as well, correct?
Let me try to summarize what I would like to make sure.
1: When no LED connected to…
Other Parts Discussed in Thread: TPS60231 Hello,
If I want to use TPS60231 as 2-Ch LED driver,
do I how to connect the D3 pin?
OPEN (NC) or GND with Pull-down resistor?

Other Parts Discussed in Thread: TPS60231 Hi,
I would like to ask a question with TPS60231 EN2 and EN1 pin
connection.
The leakage currents of EN2 and EN1, per datasheet page 3,
are on the order of µA .
Is it measured with a direct wire…
Hi,
I don't support the boost IC but you may also have a look on the TPS60231 charge pump led driver.
This IC could be a good fit as well.
Thanks & Regards,
Michael
A 0.01 Ω resistor would result in a current of 20 A.
The TLC5973 has internal current regulators that need 1 V to work. The TLC59731 has no such regulators and requires current-limiting resistors. There is not really a minimum voltage difference, but…
