GENERAL DESCRIPTION
The MAX1951A operates at a fixed frequency of 1MHz with an efficiency of up to 94%. The high operating frequency minimizes the size of external components. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improve design reliability. The MAX1951A can start up safely with a prebiased or without a preexisting output. This feature simplifies tracking supply designs for core and I/O applications and redundant supply designs. The MAX1951A is available in an 8-pin SO package and operates over the -40°C to +85°C extended temperature range. o Compact 0.385in2 Circuit Footprint o 10µF Ceramic Input and Output Capacitors, 2µH Inductor for 2A Output o Efficiency Up to 94% o 1.5% Output Accuracy Over Load, Line, and Temperature o Guaranteed 2A Output Current o Operates from 2.6V to 5.5V Supply o Adjustable Output from 0.8V to VIN o Internal Digital Soft-Soft o Short-Circuit and Thermal-Overload Protection o 1MHz Switchin...
