InnoSwitch-CP OUTPUT VOLTAGE Pin Auto-Restart Threshold
The InnoSwitch-CP has constant current regulation below 5 V, and a The VOUT pin also includes a comparator to detect when the output constant output power profile above the V threshold. The minimum PK voltage fal s below the V threshold for a duration exceeding output power delivered to the load is set by the V threshold and the OUT(AR) PK t . The secondary control er will relinquish control when it programmed constant current which is set by the resistor between VOUT(AR) detects the FEEDBACK pin has fal en below V for a time duration the ISENSE and SECONDARY GROUND pins. OUT(AR) longer than t . This threshold is meant to limit the range of VOUT(AR) constant current (CC) operation.
SR Disable Protection
On a cycle by cycle basis the SR is only engaged in the event a cycle
Output Constant-Current and Constant Power Regulation
was requested by the secondary control er and the negative edge is The InnoSwitch-CP regulates the output current through a resistor detected on the FORWARD pin. In the event the voltage on the between the ISENSE and SECONDARY GROUND pins (IS ) as well ISENSE pin exceeds approximately 3 times the IS threshold, the SR VTH VTH controls the output power in conjunction with output voltage sensed MOSFET drive is disabled until the surge current has diminished to on the VOUT pin. If constant current regulation or constant power is nominal levels. not required, this pin must be tied to the GROUND pin.
