Analog Devices / Maxim Integrated MAX20733/MAX20745 Step-Down Switching Regulators
Analog Devices MAX20733/MAX20745 Step-Down Switching Regulators are highly efficient and fully integrated regulators. The Analog Devices MAX20733/MAX20745 regulators are ideal for applications operating from 4.5V to 16V. The MAX20733 requires up to 35A maximum load. The MAX20745 requires up to 25A maximum load. The MAX20733/MAX20745 regulators offer high-efficiency power-delivery solutions with high-precision output voltages. These devices have an excellent transient response for networking, datacom, and telecom equipment.
The MAX20733/MAX20745 single chip regulators provide an extensive range of programmable features through capacitors and resistors connected to dedicated programming pins. Applying this feature, the operation can be optimized for a particular application. Thus, reducing the component count and/or setting appropriate trade-offs between the regulator's performance and system cost. Using the same design for multiple applications establishes ease of programming.
