■ 제품사양
Maximum Switching Frequency = 65 kHz Output Voltage = 16 V Output Current = 500 mA, 500 mA Control Method = Current Fall Time = 30ns Rise Time = 40ns Topology = Flyback
크기 = 5 x 4 x 1.5mm PWM Controller
타입 = Current Mode Width = 4mm
높이 = 1.5mm Maximum Operating Supply Voltage = 35 V 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
