Description
The MAX1549 dual pulse-width modulation (PWM) stepdown controller provides the high efficiency, excellent transient response, and high DC-output accuracy necessary for generating low-voltage chipset and RAM power supplies in notebook computers.
Features
- differential current-sense inputs for accurately sensing the inductor current across an external current-sense resistor in series with the output to ensure reliable overload protection. Alternatively, the controller can provide overload protection using lossless inductor current-sensing methods, lowering power dissipation and reducing system cost. Single-stage buck conversion allows the MAX1549 to directly step down high-voltage batteries for the highest possible efficiency. Very low output-volt.
