Description
Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency and Low Noise in Full Load Range
STR-W6765N
◆General description
The STR-W6765N 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 and the bottom-skip quasi-resonant operation.
◆Package
Package name: TO-220F-6L (FM207)
Sep. 2013
◆Features
Multi operation mode The operation mode switching according to load conditions achieves the optimal high efficiency and low noise power supply systems across the full load range.
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 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
800V(MIN), 1.8Ω(MAX)
◆Applications
Switching power supplies for LCD-TVs, PDP-TVs, CRT-TVs and Di...
