Description
General part information
MIC28513 Series
The MIC28513 is a synchronous step-down switching regulator with internal power switches capable of providing up to 4A output current from a wide input supply range from 4.6V to 45V. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ±1%. A constant switching frequency can be programmed from 200kHz to 680kHz. The MIC28513's Hyper Speed ControlTM and HyperLight Load® architectures allow for high VIN (low VOUT) operation and ultra-fast transient response while reducing the required output capacitance. In addition to fore-mentioned attributes, the MIC28513-1's HyperLight Load architecture provides very good light load efficiency.
The MIC28513 offers a full suite of features to ensure protection under fault conditions. These include under voltage lockout to ensure proper operation under power sag conditions, internal soft-start to reduce inrush current, foldback current limit, "hiccup" mode short-circuit protection, and thermal shutdown.
