Analog Devices MAX77540 step-down buck converter

Tuesday, 08 February, 2022 | Supplied by: Analog Devices Pty Ltd

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.
