Newest Member Of SuperSwitcher II™ Family Has 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 from an input voltage as high as 75V with maximum output current of 4A. The solution eliminates the need for a costly dual-stage conversion approach for point-of-load applications. The MIC28510 delivers up to 100W of power in a 13cm2 device – a new standard for power density. The MIC28510 integrates low-Rdson, high–side and low-side power switches to provide a highly efficient output down to 0.8V. The MIC28510 is also Any CapacitorTM stable independent of output ESR, thus solving the stability problem power supply designers face 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. The MIC28510 also offers a variety of other features that greatly simplify the design engineer's task, including a programmable switching frequency of up to 500 kHz, an enable pin for very low power shutdown, internal soft start, undervoltage lockout and internal compensation. The device also provides a host of protection features such as pre-bias safe start-up, over temperature protection, foldback current limit, short circuit protection and a -40-deg C to 125-deg C junction temperature range. The MIC28510 is available in a lead free 28-Lead 5mm x 6mm MLF® package. Less
