描述
The MAX20733 is a fully integrated, highly efficient switching regulator for applications operating from 4.5V to 16V and requiring up to 35A maximum load. This singlechip regulator provides extremely compact, high-efficiency power-delivery solutions with high-precision output voltages and excellent transient respondse for networking, datacom, and telecom equipment.
The IC offers a broad range of programmable features through capacitors and resistors connected to dedicated programming pins. Using this feature, the operation can be optimized for a specific application, reducing the component count- and/or setting-appropriate trade-offs between the regulator's performance and system cost. Ease of programming enables using the same design for multiple applications.
The MAX20733 includes protection capabilities. Positive and negative cycle-by-cycle overcurrent protection and overtemperature protection ensure a rugged design. Input undervoltage lockout shuts down the device to prevent operation when the input voltage is out of specification. A status pin provides an output signal to show that the output voltage is within range and the system is regulating.
