Thermal data
Ground.
Current return for both the signal part of the IC and the gate drive. All of the
ground connections of the bias components should be tied to a trace going to this
pin and kept separate from any pulsed current return.
Constant current (CC) regulation loop reference voltage.
An external capacitor C
circuit develops a voltage on this capacitor that is used as the reference for the
MOSFET’s peak drain current during CC regulation. The voltage is automatically
adjusted to keep the average output current constant.
Transformer demagnetization sensing for quasi-resonant operation and output
voltage monitor.
A negative-going edge triggers the MOSFET turn-on, to achieve quasi-resonant
operation (zero voltage switching).
The pin voltage is also sampled-and-held right at the end of transformer
demagnetization to get an accurate image of the output voltage to be fed to the
inverting input of the internal, transconductance-type, error amplifier, whose non-
inverting input is referenced to 2.5 V. The maximum I
must not exceed ± 2 mA (AMR) in all the Vin range conditions.
No capacitor is allowed between the pin and the auxiliary transformer.
Output of the internal transconductance error amplifier. The compensation
network is placed between this pin and GND to achieve stability and good
dynamic performance of the voltage control loop.
Not available. These pins must be connected to GND.
Not available. These pins must be left not connected.
Not internally connected. Provision for clearance on the PCB to meet safety
requirements.
Drain connection of the internal power section.
The internal high-voltage startup generator sinks current from this pin as well.
Pins connected to the internal metal frame to facilitate heat dissipation.
