SI9120-DY SMD SOP14 Switchmode Controller IC

SI9120DY SMD Sonder-IC SOP14 Switchmode Controller IC

• Typisches Ersatzteil für Schaltnetzteile 
• Universal Input Switchmode Controller
• FEATURES 10- to 450V Input Range Current-Mode Control
• 125mA Output Drive 
• Internal Start-Up Circuit
• Internal Oscillator ( 1MHz ) SHUTDOWN and RESET
• The Si9120 is a BiC/DMOS integrated circuit designed for use in low-power, high-efficiency off-line power supplies.
• High-voltage DMOS inputs allow the controller to work over a wide range of input voltages ( 10- to 450-VDC )
• Current-mode PWM control circuitry is implemented in CMOS to reduce quiescent current to less than 1.5mA
