1 / 17 page TPS2832, TPS2833 FAST SYNCHRONOUSBUCK MOSFET DRIVERS WITH DEADTIME CONTROL SLVS195C − FEBRUARY 1999 − REVISED JANUARY 2001 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Floating Bootstrap or Ground-Reference High-Side Driver D Adaptive Dead-Time Control D 50-ns Max Rise/Fall Times and 100-ns Max Propagation Delay − 3.3-nF Load D Ideal for High-Current Single or Multiphase Power Supplies D 2.4-A Typical Peak Output Current D 4.5-V to 15-V Supply Voltage Range D Internal Schottky Bootstrap Diode D Low Supply Current....3-mA Typical D −40°C to 125°C Operating Virtual Junction Temperature D Available in SOIC Package description The TPS2832 and TPS2833 are MOSFET drivers for synchronous-buck power stages. These devices are ideal for designing a high-performance power supply using switching controllers that do not have MOSFET drivers. The drivers are designed to deliver 2.4-A peak currents into large capacitive loads. The high-side driver can be configured as a ground-reference driver or as a floating bootstrap driver. An adaptive dead-time control circuit eliminates shoot-through currents through the main power FETs during switching transitions and provides high efficiency for the buck regulator. The TPS2832 has a noninverting input. The TPS2833 has an inverting input. The TPS2832/33 drivers, available in 8-terminal SOIC packages, operate over a junction temperature range of − 40 °C to 125°C.
