NCP133 PDF Datasheet

NCP133 500 mA, Very Low Dropout Bias Rail CMOS Voltage Regulator The NCP133 is a 500 mA VLDO equipped with NMOS pass transistor and a separate bias supply voltage (VBIAS). The device provides very stable, accurate output voltage with low noise suitable for space constrained, noise sensitive applications. In order to optimize performance for battery operated portable applicatio

NCP1337 PWM Current-Mode Controller for Free Running Quasi-Resonant Operation The NCP1337 combines a true current mode modulator and a demagnetization detector which ensures full Borderline/Critical Conduction Mode in any load/line conditions together with minimum drain voltage switching (Quasi−Resonant operation). The transformer core reset detection is done internally, wit

NCP1338 PWM Current-Mode Controller for Free Running Quasi-Resonant Operation The NCP1338 combines a true current mode modulator and a demagnetization detector which ensures full Borderline/Critical Conduction Mode in any load/line conditions together with minimum drain voltage switching (Quasi-Resonant operation). The transformer core reset detection is done internally, withou

NCP1339 High-Voltage, QuasiResonant Controller featuring Valley Lock-Out and Power Saving Mode The NCP1339 is a highly integrated quasi−resonant flyback controller capable of controlling rugged and high−performance off−line power supplies as required by adapter applications. With an integrated active X−cap discharge feature and power savings mode, the NCP1339 can enabl
