The PT4498N from Texas Instruments is a high-performance 20A current booster module. It is specifically designed to augment the capabilities of the PT4484 Excalibur™ DC/DC converter, allowing for synchronized operation and increased output current.
This booster module accepts an input voltage ranging from 36V to 75V and provides a significant current boost, effectively doubling the PT4484's output current capacity to 40A when used in conjunction. The PT4498N utilizes the same 26-pin copper case package as its companion regulator, ensuring compatibility in form factor.
Key features include synchronized operation with the PT4484, high efficiency, and a robust input voltage range suitable for various power supply applications. It is not a standalone product and requires the PT4484 for proper functionality. Refer to the PT4484 datasheet for detailed performance specifications.
The PT4498N is housed in a 26-pin copper case package. Standard application guidelines suggest input capacitors of 33µF and a minimum of 330µF output capacitance per booster module for optimal performance and transient response.
The module operates reliably within an input voltage range of 36V to 75V.
The component is housed in a 26-pin copper case.
It is specifically designed to boost the Texas Instruments PT4484 voltage regulator.
The module provides a 20A current boost capability.
The component utilizes a through-hole mounting type.
