|The SuperSwitcher II™ family features Micrel's Hyper Speed Control™, delivering ultra-fast transient response and minimizing output capacitance, while achieving highest power density. The MIC28510 is a wide-input, synchronous switching regulator IC that provides step-down conversion with better than 94 percent peak efficiency. With an input voltage as high as 75 V and a maximum output current of 4 A, the solution eliminates the need for a costly dual-stage conversion approach for point-of-load applications. The MIC28510 delivers up to 100 W of power in a 13cm2 device.
The MIC28510 integrates low-RDSON, high and low-side power switches to provide a highly efficient output down to 0.8 V. The MIC28510 is also Any Capacitor™ stable, independent of output ESR, thus solving the stability problem power supply designers faced with distributed output capacitance.
By combining an exceptionally wide input voltage range, superior stability and transient response with innovative packaging the chip ensures the best power density and thermal performance across the entire load range. The solution delivers unprecedented performance and flexibility, placing the MIC28510 in the sweet spot for designers tackling the industry’s most demanding applications.
