The TPS2838/39/48/49 series are MOSFET drivers designed for high-performance synchronous power supplies. They can provide up to 4A peak current and are ideal for use with power supply controllers that do not have on-chip drivers.
The TPS2838/39/48/49 devices are MOSFET drivers designed for high-performance synchronous power supplies. They can source and sink up to 4-A peak current at a 14-V drive voltage, making them ideal for use with power supply controllers that lack on-chip drivers. These devices feature an integrated 150-mA regulator to optimize gate drive voltage for specific MOSFETs.
| Peak Current | 4-A peak current at VDRV of 14 V |
|---|---|
| Supply Voltage Range | 10-V to 15-V |
| Regulator Output Current | 150-mA |
The devices are capable of sourcing and sinking up to 4-A peak current at a 14-V drive voltage.
It is recommended that a capacitor with a minimum value of 1 uF be connected from Voc to PGND.
The devices operate within an ambient temperature range of -40°C to 125°C.
