A6052

enefits

• 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

• Built-in Leading Edge Blanking function
• Built-in High Speed Latch Release function, releasing the latch shutdown immediately at turning off AC supply
• Two-chip structure, with a controller and a power MOSFET with guaranteed avalanche energy available to simplify surge absorber circuits
• Protection functions: ▫ Brown-In and Brown-Out Protection function: auto-restart, prevention of excess input current and heat rise at low input voltage ▫ Overcurrent Protection function (OCP): pulse-by-pulse built-in compensation circuit to minimize OCP point variation on AC input voltage ▫ Overload Protection function (OLP): auto-restart, built-in timer, reduces heat during overload condition, and no external components required ▫ Overvoltage Protection function (OVP): latched shutdown ▫ Thermal Shutdown Protection function (TSD): shutdown latches device off to prevent continuous oscillation
