LP87524B-Q1: About current value setting of each channel

Junya Kato

Part Number: LP87524B-Q1

Hello Team,

Is it possible to set the current value of each channel as follows?
And, is it possible to realize if the thermal design can be cleared?
Is output of 5-6A difficult to realize without connecting output 2 channels?

OUT1：Iout_max = 5-6A
OUT2：Iout_max = 1A
OUT3：Iout_max = 0.5-1A
OUT4：Iout_max = 0.5-1A

Best regards,
Kato

Kato,
I have forwarded your question to our product specialist for this part. Someone should respond soon.

Hello Kato,

5-6A is not possible with single channel, two phases would be needed for it.

Thanks.

Hello Tomi-san,

Is the reason why single channel is difficult for thermal problems? Or because it can not be set the register?
By the way, I want to make the voltage as follows.

OUT1：1.0V, 5-6A
OUT2：3.3V, 1A
OUT3：1.35V,0.5-1A
OUT4：1.8V, 0.5-1A

Best regards,
Kato

Hello Kato-san,

Maximum current per phase is 4A DC load. Limiting factor is the power FET current ratings.

Thanks.

Best regards,
