Drain connection of the internal power MOSFET. The internal high voltage start-up
generator sinks current from this pin.
Not internally connected. Provision for clearance on the PCB.
Supply pin of the IC. An electrolytic capacitor is connected between this pin and ground.
The internal start-up generator charges the capacitor until the voltage reaches the start-
up threshold. The PWM is stopped if the voltage at the pin exceeds a certain value.
Output of the Error Amplifier. Used for control loop compensation or to directly control
PWM with an optocoupler.
Inverting input of the Error Amplifier. The non-inverting one is internally connected to a
2.5V± 2% reference. This pin can be grounded in some feedback schemes.
Connection of both the source of the internal MOSFET and the return of the bias current
of the IC. Pins connected to the metal frame to facilitate heat dissipation.
Brownout Protection. If the voltage applied to this pin is lower than 2.5V the PWM is
disabled. This pin is typically used for sensing the input voltage of the converter through
a resistor divider. If not used, the pin can be either left floating or connected to Vcc
through a 15 k
Current return for the bias current of the IC.
Connection of the source of the internal MOSFET. Pins connected to the metal frame to
facilitate heat dissipation.
