EVBUM2670 NCL30125 Daughter Board User's Manuel
● The NCL30125 is a fixed−frequency current−mode controller featuring the Dynamic Self−Supply (DSS). The controller hosts an adjustable switching frequency with jittering function operated in peak current mode control. When the power on the secondary side drops drastically, the part enters skip cycle while limiting the peak current that insures the output voltage regulation and excellent efficiency in light load condition. It features a timer−based fault detection that ensures the detection of overload and a brown−out protection against low input voltages.
●Features:
■ Integrated High−side Driver
■Adjustable Switching Frequency up to 1 MHz with Frequency Jittering
■Peak Current−mode Control
■Skip Mode to Maximize Performance in Light Load Conditions
■High−voltage Current Source with DSS
■Brown−out (BO) Detection
■Adjustable Soft−start Duration
■15−ms Timer−based Short−circuit Protection with Auto−recovery or Latched Operation
■Latched OVP/OTP Input for Improved Robustness
■+0.9 A / −1.2 A Peak Source / Sink Drive Capability
