Analog Devices MAX77540 step-down buck converter

Analog Devices has introduced the MAX77540 step-down buck converter, which provides single-stage power conversion in multi-cell battery applications, such as augmented reality/virtual reality headsets, land mobile radios and digital single-lens reflex cameras.

The buck converter features peak efficiency and wafer level packaging smaller than traditional quad flat no-lead packages.

Multi-cell battery applications require two-stage power conversion and long battery life in the smallest package possible. With the MAX77540 the design engineer can create either dual 3 A or a single 6 A output(s).

Default power on configuration only requires two external resistors and an I²C interface allows further control for advanced power management techniques. External frequency tracking and spread spectrum modulation provide low electromagnetic interference power conversions for data sensing and processing equipment.

Features include: wide 4–16 V input voltage range and two 3 A switching phases provide single step conversions to core voltages from USB-C rails and 2S and 3S multi-cell batteries.
