| 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. With a supply range up to 35 V, the controller hosts a jittered 65 or 100-kHz switching circuitry operated in peak current mode control.Fixed-Frequency 65-kHz or 100-kHz Current-Mode Control Operation 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 64-ms Timer-Based Short-Circuit Protection with Auto-Recovery or Latched Operation More information: | | Maximum Switching Frequency: | 65 kHz | Output Voltage: | 16 V | Output Current: | 500 mA, 500 mA | Control Method: | Current | Number of Outputs: | 1 | Fall Time: | 30ns | Mounting Type: | Surface Mount | Package Type: | SOIC | Rise Time: | 40ns | Pin Count: | 7 | Topology: | Flyback | Dimensions: | 5 x 4 x 1.5mm | Maximum Duty Cycle: | 84% | Length: | 5mm | PWM Controller Type: | Current Mode |
