The Texas Instruments PT4498A is a high-performance 20A current booster module. It is specifically designed to augment the PT4484 Excalibur™ DC/DC converter, allowing for increased current output up to 40A when operated in synchronization.
This booster module operates within an input voltage range of 36V to 75V. It features a 26-pin copper case package and is intended for use in conjunction with the PT4484, not as a standalone product. The PT4498A adds a parallel output stage to the PT4484, enabling synchronized operation for enhanced performance.
Refer to the PT4484 datasheet for detailed performance specifications. The PT4498A utilizes the same package options as its companion regulator, facilitating integration into existing designs. Proper output capacitance is required for stable operation.
The input voltage range for the PT4498A is 36V to 75V.
The PT4498A provides a 20A current boost.
The PT4498A comes in a 26-pin copper case package.
The Moisture Sensitivity Level (MSL) for the PT4498A is 1 Unlimited.
