PIN CONFIGURATION PIN DESCRIPTIONS PART NUMBER TEMPERATURE RANGE PACKAGE PINS PACKING METHOD TOP MARK ACT334US-T -40°C to 85°C SOT23-6 6 TAPE & REEL FSTA NAME DESCRIPTION 1 SW Switch Drive. Switch node for the external NPN transistor. Connect this pin to the external power NPN’s emitter. This pin also supplies current to VDD during startup. 2 GND Ground. 3 BD Base Drive. Base driver for the external NPN transistor. 4 VDD Power Supply. This pin provides bias power for the IC during startup and steady state operation. 5 FB Feedback Pin. Connect this pin to a resistor divider network from the auxiliary winding. 6 CS Current Sense Pin. Connect an external resistor (RCS) between this pin and ground to set peak current limit for the primary switch. The peak current limit is set by (0.396V × 0.9) / RCS. For more detailed information, see Application Information. PIN SOT23-6 ACT334US-T ORDERING INFORMATION Rev 2, 14-Nov-12 |
