When the voltage at this pin falls below 0.4V,chip switching-frequency reduces to a mu ch lower frequency. No connection.Keep floating. Enable pin. A TTL low will shut down the chip and high enable the chip. This pin may also be used to synchronize the part to nearly twice the base frequency. If synchronization is not used, this pin should be either tied high or left floating for normal operation. Input power supply pin. Supply power to the IC and should have a bypass capacitor connected to AGND Analog ground. Provide a clean ground for the co ntroller circuitry and should not be in th e path of large cu rrents.This pin is connected to the IC substrate. Power ground. This pin is the ground connection for the emitter of the power switching transistor.Connectio n to a good ground plane is essential. High current switch pin. Connect to the collector of the internal power switch. The open voltage across the power switch can be as high as 40V. To minimize radiation, use a trace as short as practical. 2/6 Free Datasheet http://../ ABSOLUTE MAXIMUM RATINGS (Ta=25 ° C) Characteristic Input Voltage Switch Input Voltage, Maximum Operating Junction Temp erature Storage Temperature Lead Temp erature(Solderin...
