| Abstract: | NCP 1337, a PWM current-mode controller for free running quasi-resonant operation, combining a true current mode modulator and a demagnetization detector which ensures full borderline/critical conduction mode in any load/line conditions, is introduced in this paper. Especially, its two important technologies soxyless detection and soft ripple mode, are analyzed in detail. Based on NCP1337, a high efficiency isolating quasiresonant power supply is designed. |
