3 / 36 page  TOP232-234 B 7/01 3 Figure 2. Functional Block Diagram. Pin Functional Description DRAIN (D) Pin: High voltage power MOSFET drain output. The internal start- up bias current is drawn from this pin through a switched high- voltage current source. Internal current limit sense point for drain current. CONTROL (C) Pin: Error amplifier and feedback current input pin for duty cycle control. Internal shunt regulator connection to provide internal bias current during normal operation. It is also used as the connection point for the supply bypass and auto-restart/ compensation capacitor. MULTI-FUNCTION (M) Pin: Input pin for OV, UV, line feed forward with DC MAX reduction, external set current limit, remote ON/OFF and synchronization. A connection to SOURCE pin disables all functions on this pin and makes TOPSwitch-FX operate in simple three terminal mode (like TOPSwitch-II). FREQUENCY (F) Pin: (Y package only) Input pin for selecting switching frequency: 132 kHz if connected to SOURCE pin and 66 kHz if connected to CONTROL pin. Figure 3. Pin Configuration. PI-2535-083099 The switching frequency is internally set for 132 kHz only operation in P and G packages. SOURCE (S) Pin: Output MOSFET source connection for high voltage power return. Primary side control circuit common and reference point.
