Product Details
The NCP1239 is a fixed-frequency current-mode controller featuring a high-voltage start-up current source to provide a quick and lossless power-on sequence. This function greatly simplifies the design of the auxiliary supply and the VCC capacitor by activating the internal start-up current source to supply the controller during start-up, transients, latch, stand-by etc.
Features
• Fixed-Frequency 65-kHz or 100-kHz Current-Mode ControlOperation
• Frequency Foldback Down to 26 kHz and Skip Mode to
Maximize Performance in Light Load Conditions
• Adjustable Over Power Protection (OPP) Circuit
• High-Voltage Current Source with Brown-Out (BO) Detection
• Internal Slope Compensation
• Internal Fixed Soft-Start
• Frequency Jittering in Normal and Frequency Foldback Modes
