TPS61169: IC recommend

Charlie Xiao

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

Hi Charlie,

what do you mean of "1.5V/1A and 18V/1A"? Is it the input voltage?

Hi Patrick,

In practical applications, 5V input or 18V input, and the Iout is no more than 1A. 5V input is preferred as it is cheaper. Thanks.

Hi Charlie,

Could you give a more specific LED current requirement? I think "no more than 1A" is too general.

And how many LEDs in a series?
