Power IC for Quasi-Resonant Type Switching Power Supply
with High Efficiency and Low Noise in Full Load Range
STR-W6750F
General description
The STR-W6750F 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.
Package
Package name: TO-220F-6L (FM207)
Sep. 2013
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 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
