Overview

MAX5099 19-4112; Rev 0; 5/08 EVAALVUAAILTAIOBNLEKIT Dual, 2.
2MHz, Automotive Synchronous Buck Converter with 80V Load-Dump Protection General Description The MAX5099 offers a dual-output, high-switching-frequency DC-DC buck converter with an integrated highside switch.
The MAX5099 integrates two low-side MOSFET drivers to allow each converter to drive an external synchronous-rectifier MOSFET.
Converter 1 delivers up to 2A output current, and converter 2 can deliver up to 1A of output current.
The MAX5099 integrates load-dump protection circuitry that is capable of handling load-dump transients up to 80V for automotive applications.
The load-dump protection circuit utilizes an internal charge pump to drive the gate of an external n-channel MOSFET.
When an overvoltage or loaddump condition occurs, the series protection MOSFET absorbs the high voltage transient to prevent damage to lower voltage components.
The DC-DC converter operates over a wide 4.
5V to 19V operating voltage range.
