MC 44608P40 DIP8 40kHz PWM Controller (13122)
The MC44608 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 1W while delivering 300mW in a 150W SMPS. • Integrated Start-Up Current Source • Lossless Off-Line Start-Up • Direct Off-Line Operation • Fast Start-Up
