FEATURES
• High hFE and low V
• High collector current capability: IC maximum 4 A
• High efficiency leading to less heat generation.
APPLICATIONS
• Medium power peripheral drivers (e.g. fan and motor)
• Strobe flash units for DSC and mobile phones
• Inverter applications (e.g. TFT displays)
• Power switch for LAN and ADSL systems
• Medium power DC-to-DC conversion
• Battery chargers.
