STR-A60xxM
Current Mode Control PWM Regulator IC
For Switching Power Supplies
Features and Benefits
▪ Small DIP8 package with 8 to 24 W power output 230 VAC
▪ Current Mode PWM control with 67 kHz switching
frequency
▪ 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 < 25 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

Description
The STR-A60xxM 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-A60xxM internal MOSFET has a VDSS of
650 V(min) or 800 V(min), and an RDS(on) of 1.9 to 19.2 Ω
with a frequency of 67 kHz. Power output is rated at
8 to 24 W at 230 VAC input and 5 to 20 W at wide input range
(85 to 265 VAC).
The device is provided in an industry-standard DIP-8 package,
with pin 6 removed for increased isolation.
Applications:
For switching power supplies used in:
• Battery chargers for cell phones, digital cameras,
video cameras, shavers, emergency lights
• Stand-by power for LCD TVs, desktop PCs, LB Printers,
audio equipment
• Small switched-mode power supplies for inkjet printers,
DVD/CD players, set-top boxes
• Auxiliary power supplies for A/C, refrigerators, washers,
dish washers, and other white goods
