DIP8 package, connecting one side (pin5 to pin8) with a power MOSFET drain.

The distance between high voltage terminal and low voltage terminal is 0.762mm (0.3inches), and the wider drain trace is available to enhance thermal dissipation of the IC.

Current Mode PWM control

Built-in Random Switching Function, reducing EMI noise, and simplifying EMI filters, by the slight random change of PWM frequency, fOSC.

Auto Standby Function (Input Power, PIN < 25mW at no load)

Normal load operation – PWM mode

Light load operation – Standby mode (Burst oscillation)
