Regulator -> D2Flex or D2Flex -> Regulator

[greencardigan]

Hi,

I want to drive a SST-90 with a D2flex pwm controller and some current reguators. Probably 3 of the 2.8A KD 8xAMC7135 boards.

Should I connect Batteries -> D2Flex -> regulators -> LED

or

Batteries -> regulators -> D2Flex -> LED

:thinking:

Or should I use the D2Flex to PWM the AMC7135 regulators?


Anyone out there? :wave:

There's me, at least - I'm interested in the answer to your question too

See http://www.taskled.com/techhipcc.html Scroll to the very bottom and examine the last photo.

For both links, note which board you connect to Batt+ and Batt-. You should have the answer to your question.

Thanks foir the HipCC info.

It's probably a question for George, but does enabling the PWM mode on the D2Flex as described on the HipCC page give an active high PWM pulse train?

Thanks.

An email from George states the PWM connection, when enabled, will be active low PWM.

The PWM pad on d2flex is only active when it is configured for driving a hipCC etc and is then only a signal level (high to turn off the driver, low to turn it on - i.e. active low going PWM pulse train).
