STR-X6759F
description
The STR- X6759F is power IC for quasi-resonant type switching power supply, incorporating a power MOSFET and a controller IC. The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation.
- 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);...
