Hello guys,
One of my customers is looking LED driver which can control small current like less than 1mA with analog dimming mode.
I think TPS54200 could drive the small current. The customer requirements are the follows.
Input voltage: 15V
Output voltage: 6.4V(2 LED)~12.8V(4 LED)
Topology: Buck
Channel #: 1ch
Output current: 500mA(Max), ~ Less than 1mA(Min)
Dimming method: Analog dimming (By continuous current)
Current change period: Every 33ms (They want to change the output current every 33ms.)
Could you please give me your reply to the following question?
Q. Can TPS54200 meet these requirement and control small current like less than 1mA with analog dimming mode?
Also if you have any other device can be recommended for their requirement, could you please tell me the device number?
Your reply would be much appreciated.
Best regards,
Kazuya.
