ADP2504 Over-current

Question asked by GTB on Jun 19, 2013

My customer will be using this part to driver an Led at 500mA Constant current, can

you advise re the following two questions ?

 

1. The part has s/c protection built in but I cannot see a voltage clamp on
the output for o/c protection.  If configured in constant current mode for
driving an LED, will I need an external zener to limit Vout or has it got a
built in protection circuit?


2. The eval board has been ordered can the board be reconfigurable to drive an LED
at 500mA constant current, or is the eval board limited to fixed vout in CV mode?
