■Functional descriptions
1. CV/CC mode control
ELM651DA provides CV/CC function. The CV (constant voltage) function is implemented to deliver a regu-
lated output voltage for the output terminal, and the CC (constant current) function is to limit output current to
be a limited value to prevent the device damaged due to output short circuit or over current condition.
2. Soft start function
ELM651DA is composed of built-in internal soft start function to prevent a large surge current happening
when during start-up period due to the surge current charging output filter capacitors.
3. Output over-voltage protection
ELM651DA provides output over-voltage protection function. When output over-voltage happens, ELM651DA
shuts down and recovers to normal state automatically if output over-voltage is released.
4. Output short-circuit protection
ELM651DA provides output short-circuit protection function. When output short-circuit happens, ELM651DA
shuts down and recovers to normal state automatically if output short-circuit is released.
