Micrel MIC28510YJL Synchronous DC/DC Buck Regulator

Micrel MIC28510YJL DC/DC Buck Regulator

Micrel MIC28510YJL 75V/4A Hyper Speed Control™ Synchronous DC/DC Buck Regulator is an adjustable frequency device featuring unique adaptive on–time control architecture. MIC28510 operates over an input supply range of 4.5V to 75V and provides a regulated output of up to 4A of output current. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ±1%. Micrel's Hyper Speed Control architecture allows for ultra–fast transient response while reducing the output capacitance and also makes (High VIN) / (Low VOUT) operation possible. This adaptive tON ripple control architecture combines the advantages of fixed–frequency operation and fast transient response in a single device. This Micrel device offers a full suite of protection features to ensure protection of the IC during fault conditions.
