Pin Configuration

Pin Definitions
Pin Number Pin Name Pin Function Description
1Drain
SenseFET Drain. This pin is the high-voltage power SenseFET drain. It is
designed to drive the transformer directly.
2GNDGround. This pin is the control ground and the SenseFET source.
3V
CC
Power Supply. This pin is the positive supply voltage input. During startup,
the power is supplied through the startup resistor from DC link. When V
CC
reaches 12V, the power is supplied from the auxiliary transformer winding.
4 Feedback (FB)
Feedback. This pin is internally connected to the inverting input of the PWM
comparator. The collector of an opto-coupler is typically tied to this pin. For
stable operation, a capacitor should be placed between this pin and GND. If
the voltage of this pin reaches 6.0V, the overload protection is activated, re-
sulting in shutdown of the FPS.
5 N.C. This pin is not connected.
6 I_limit
Current Limit. This pin is for the pulse-by-pulse current limit level program-
ming. By using a resistor to GND on this pin, the current limit level can be
changed. If this pin is left floating, the typical current limit is 2.0A.

Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables
are not guaranteed at the absolute maximum ratings.

Notes:
1. Pulse Test: Pulse width ≤ 300µS, duty ≤ 2%
2. These parameters, although guaranteed at the design, are not tested in mass production.
3. These parameters indicate the inductor current. Where packages are I2PAK or D2PAK, this should be decreased to
2.0A by external resistor.
4. MOSFET switching time is essentially independent of operating temperature.
