Converter Offline Flyback Topology 60kHz ~ 74kHz TO-220F-6L

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

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): Auto-restart

Thermal Shutdown Protection function (TSD): Auto-restart
