The MAX5070BASA-T is an integrated circuit (IC) component designed for power management applications. It is a high-performance, fixed-frequency, synchronous step-down DC-DC converter with built-in features that make it suitable for a wide range of power supply designs.
One of the key features of the MAX5070BASA-T is its wide input voltage range capability, which extends from 2.2V to 20V. This makes it compatible with various input sources, including single-cell Li-ion batteries, multi-cell batteries, intermediate bus voltages, and industrial supplies.
The IC offers excellent efficiency, as it integrates four main power elements - two high-side and two low-side MOSFETs. These power MOSFETs enable the converter to achieve high efficiency while maintaining a low voltage drop. Additionally, it incorporates a high-performance current mode controller that ensures stable and high-power conversion efficiency across the entire input voltage range.
Another notable feature of the MAX5070BASA-T is its synchronous rectification capability, which further enhances efficiency by minimizing power losses during the conversion process. By utilizing synchronous rectification, the IC reduces the power dissipated by the freewheeling diode commonly found in traditional step-down converters.
The IC provides a fixed-frequency operation at 530kHz, which helps minimize interference with sensitive RF circuits
