RoHS: | Compliant |
The MIC28511 is a synchronous step-down switching regulator with internal power switches capable of providing up to 3A output current from a wide input supply range from 4.6V to 60V. 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 Hyper Speed Control™ and HyperLight Load® architectures of the MIC28511 allow for high VIN (low VOUT) operation and ultra-fast transient response while reducing the required output capacitance and providing very good light load efficiency.
The MIC28511 offers a full suite of protection features to ensure protections under fault conditions. These include under-voltage lockout to ensure proper operation under power sag conditions, internal soft-start to reduce inrush current, fold-back current limit, “hiccup†mode short-circuit protection, and thermal shutdown.
