詳細(xì)介紹
The HT44608N is a high performance voltage mode controller designed for off–line converters. This high voltage circuit that integrates the start–up current source and the oscillator capacitor, requires few external components while offering a high flexibility and reliability. The device also features a very high efficiency stand–by management consisting of an effective Pulsed Mode operation. This technique enables the reduction of the stand–by power consumption to approximately 1.0 W while delivering 300 mW in a 150 W SMPS. ● Integrated Start–Up Current Source ● Lossless Off–Line Start–Up
