The Texas Instruments PT4497N is a high-performance 8.5A current booster module, specifically designed to augment the capabilities of the PT4486 DC-DC converter. This booster adds a parallel output stage, enabling synchronized operation with the PT4486 to achieve a combined output current of up to 17A. It is not a standalone product and requires the PT4486 for operation.
The PT4497N supports a wide input voltage range from 36V to 75V and provides a 100W output power capability. It features synchronized operation with the PT4486, ensuring seamless integration and performance. The booster is housed in a 26-pin copper case package, sharing the same package options as the PT4486.
Standard application circuits suggest the use of input capacitors (e.g., 33µF) to reduce input ripple and output capacitors (a minimum of 33µF per booster module) for proper operation and transient response. The PT4497N is designed for applications requiring increased current capacity from the PT4486 converter.
The PT4497N provides an 8.5A current boost, which can increase the PT4486's output current up to 17A.
The input voltage range for the PT4497N is 36V to 75V.
The PT4497N has an output power rating of 100W.
The PT4497N is supplied in a 26-pin copper case package.
The Moisture Sensitivity Level (MSL) for the PT4497N is 1 Unlimited.
