MAX799, Step-Down Controllers

19-0221; Rev 4; 9/05 KIT ATION EVALU E L B AVAILA Step-Down Controllers with Synchronous Rectifier for CPU Power ____________________________.
The MAX796/MAX797/MAX799 high-performance, stepdown DC-DC converters with single or dual outputs provide main CPU power in battery-powered systems.

Features

* 96% Efficiency
* 4.5V to 30V Input Range
* 2.5V to 6V Adjustable Output
* Preset 3.3V and 5V Outputs (at up to 10A)
* Multiple Regulated Outputs
* +5V Linear-Regulator Output
* Precision 2.505V Reference Output
* Automatic Bootstrap C

Applications

* This secondary feedback path improves cross-regulation of positive (MAX796) or nega tive (MAX799) auxiliary outputs. The MAX797 has a logic-controlled and synchronizable fixed-frequency pulse-width-modulating (PWM) operating mode, which reduces noise and RF interference in sensi tive mobile-communi
