- Package
Package name: TO-220F-6L (FM207)
- Features
- Quasi-resonant operation mode Achieves the optimal high efficiency and low noise power supply systems.
- Current mode control
- Built-in PWM oscillator The PWM operates with the minimum frequency of around 22k Hz, until the quasi-resonant signal bees valid, reduces the stress on ponents at startup and load-shorted.
- Built-in soft start function
- Step-drive function, reducing switching noise
- Input pensation at overcurrent The function reduces the distortion of overcurrent operation point to AC input voltage change by adding three ponents.
- Avalanche energy guaranteed by two chips structure (Simplification of surge absorbing circuit)
- Protection functions Overcurrent protection (OCP); Pulse-by-pulse Overload protection (OLP); latched shutdown Overvoltage protection (OVP); latched shutdown
- Specification
MOSFET 650V(MIN), 0.73Ω(MAX)
- Applications
Switching power supplies for
- LCD-TVs, PDP-TVs, CRT-TVs and Digital consumer equipment
- Home appliances
- OA equipments
- Industry machines
- munication devices
