The MAX767CAP+ is a monolithic BiCMOS IC from Analog Devices that functions as a high-efficiency, synchronous buck controller. It is specifically designed to convert a fixed 5V supply into a tightly regulated 3.3V output, making it suitable for local 5V-to-3.3V DC-DC conversion applications, microprocessor daughterboards, and power supplies up to 10A or more.
Key features include over 90% efficiency, a low quiescent supply current of 700µA, and a standby supply current of 120µA. The device supports an input voltage range of 4.5V to 5.5V and operates at a high frequency of 300kHz, which enables the use of very small, low-cost external surface-mount components, such as a 3.3µH inductor for 5A output.
The all N-channel construction and synchronous rectification contribute to reduced cost and high efficiency, eliminating the need for heatsinking. Output capacitance requirements are also low, saving board space and cost. The MAX767CAP+ is available in a compact 20-pin SSOP package, ideal for space-constrained designs.
This controller is well-suited for applications requiring a standard 5V to 3.3V DC-DC conversion up to 10A, including high-accuracy power supplies for processors like Pentium P54C and PowerPC.
