STR-W605xS
Current Mode Control PWM Regulator IC
For Switching Power Supplies
Features and Benefits
▪ TO-220F power package with 30 to 90 W power output
▪ Current Mode PWM control
▪ Built-in Random Switching function, reducing EMI noise,
and simplifying EMI filters, and therefore reducing cost
▪ Built-in Slope Compensation function, avoiding
subharmonic oscillation
▪ Built-in Auto Standby function (Input Power, PIN < 30 mW
at no load)
▫ Normal operation: PWM mode
▫ Light load operation: Standby mode (burst oscillation)
▪ Built-in Audible Noise Suppression function during
Standby mode
▪ Built-in Startup Circuit, reducing power consumption in
standby operation, and eliminating external components.
▪ Bias-Assist function, improving startup operation,
suppressing VCC voltage drop in operation, and allowing
use of smaller VCC capacitor
▪ Built-in Leading Edge Blanking function

Package: 6-Pin fully molded
TO-220F-6L (FM207)
Description
The STR-W605xS series are power ICs for switching power
supplies, incorporating a power MOSFET and a current mode
PWM controller IC. Including a startup circuit and a standby
function in the controller, the product achieves low power
consumption, low standby power, and high cost-effectiveness
power supply systems with few external components.
The STR-W605xS internal MOSFEThas aVDSS of 650V(min),
and an RDS(on) of 1.9 Ω (max) to 3.95 Ω (max) with a frequency
of 67 kHz. Power output is rated at 45 to 90 W at 230 VAC
input and 30 to 60 W at wide input range (85 to 265 VAC).
The device is provided in an industry-standardTO-220 package,
with heatsink mounting flange and pin 2 removed for increased
supply isolation.
