| 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 Más información: | | Frecuencia de Conmutación Máxima: | 65 kHz | Tensión de Salida: | 16 V | Corriente de Salida: | 500 mA, 500 mA | Método de Control: | Corriente | Número de Salidas: | 1 | Tiempo de Bajada: | 30ns | Tipo de Montaje: | Montaje superficial | Tipo de Encapsulado: | SOIC | Tiempo de Subida: | 40ns | Conteo de Pines: | 7 | Topología: | Flyback | Dimensiones: | 5 x 4 x 1.5mm | Ciclo de Trabajo Máximo: | 84% | Longitud: | 5mm | Tipo de Controlador PWM: | Modo de corriente |
