Beschreibung
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
