Description
General part information
MAX767 Series
The MAX767 is a high-efficiency, synchronous buck controller IC dedicated to converting a fixed 5V supply into a tightly regulated 3.3V output. Two key features set this device apart from similar, low-voltage step-down switching regulators: high operating frequency and all N-channel construction in the application circuit. The 300kHz operating frequency results in very small, low-cost external surface-mount components.The inductor, at 3.3µH for 5A, is physically at least five times smaller than inductors found in competing solutions. All N-channel construction and synchronous rectification result in reduced cost and highest efficiency. Efficiency exceeds 90% over a wide range of loading, eliminating the need for heatsinking. Output capacitance requirements are low, reducing board space and cost.The MAX767 is a monolithic BiCMOS IC available in 20-pin SSOP packages. For other fixed output voltages and package options, please consult the factory.ApplicationsLocal 5V-to-3.3V DC-DC ConversionMicroprocessor DaughterboardsPower Supplies Up to 10A or More
