Internal Schottky Diode Reduces Part Count  
Synchronous or Nonsynchronous Operation  
The devices feature VDRV to PGND shoot-  
through protection with adaptive/adjustable  
deadtime control. The deadtime, for turning on the  
high-side FET from LOWDR transitioning low, is  
adjustable with an external capacitor on the  
DELAY pin. This allows compensation for the  
effect the gate resistor has on the synchronous  
FET turn off. The adaptive deadtime prevents the  
turning on of the low-side FET until the voltage on  
the BOOTLO pin falls below a threshold after the  
high-side FET stops conducting. The high-side  
drive can be configured as a ground referenced  
driver or a floating bootstrap driver. The internal  
Schottky diode minimizes the size and number of  
external components needed for the bootstrap  
driver circuit. Only one external ceramic capacitor  
is required to configure the bootstrap driver.  
DESCRIPTION  
The TPS2838/39/48/49 devices are MOSFET  
drivers designed for high-performance  
synchronous power supplies. The drivers can  
source and sink up to 4-A peak current at a 14-V  
drive voltage. These are ideal devices to use with  
power supply controllers that do not have on-chip  
drivers. The low-side driver is capable of driving  
loads of 3.3 nF in 10-ns rise/fall times and has  
40-ns propagation delays at room temperature.  
The MOSFET drivers have an integrated 150-mA  
regulator, so the gate drive voltage can be  
optimized for specific MOSFETs. The TPS2848  
and TPS2849 have a fixed 8-V drive regulator,  
while the TPS2838/39 allow the drive regulator to  
be adjusted from 4 V to 14 V by selection of two  
external resistors.
