Overview
Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency and Low Noise in Full Load Range STR-X6759B Sep.
2013 ◆General description The STR- X6759B 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 22kHz, until the quasi-resonant signal becomes valid, reduces the stress on components at startup and load-shorted.
 Built-in soft start function  Step-drive function, reducing switching noise  Input compensation at overcurrent The function reduces the distortion of overcurrent operation point to AC input voltage change by adding three components.
 Avalanche energy guaranteed by two chips s...
