Devices for SW Power Supply
(4) Devices for Power MOSFET Buffer
1) Low Side Driver ExPD [MOSFET, IGBT Gate driver IC]
[Application]
• PDP, LCD-backlight, inverter light, liquid crystal projector, HID drive, motor drive, half-bridge/full-bridge power supply, etc.
[ExPD Use Example]
• Withstand voltage of 25V is assured.
• 2 low side drivers in
• TTL/CMOS compatible
(V IH =2.6V or less at V DD =4.5 to 25V)
• High-speed switching time
(t r /t f =typ 25ns, at 1000pF load [TND301S])
ExPDs
