MAX17602ASA+ High-Efficiency, Synchronous Step-Down DC-DC Converter

The MAX17602ASA+ from Maxim Integrated is a highly efficient, compact, synchronous step-down DC-DC converter designed for a wide range of applications. This versatile power management integrated circuit (PMIC) is capable of delivering up to 1A of output current, making it an ideal solution for powering portable devices, microcontrollers, and other low-power electronics.

With an input voltage range of 4.5V to 36V, the MAX17602ASA+ is well-suited for systems that experience wide variations in supply voltage. This flexibility allows it to accommodate a variety of power sources, including single-cell Li-ion batteries, multi-cell battery packs, and industrial power rails.

The device operates at a fixed switching frequency of 500kHz, which provides an optimal balance between efficiency and component size. The high frequency allows for the use of small, low-cost inductors and capacitors, reducing the overall footprint and bill of materials (BOM) for the power supply design.

One of the key features of the MAX17602ASA+ is its synchronous rectification topology. By integrating low RDS(ON) MOSFETs, the converter minimizes power losses and achieves high efficiency across a wide load range. This feature not only extends battery life in portable applications but also reduces thermal stress, enhancing system reliability.

The device also includes a range of protection features to safeguard against abnormal operating conditions. These include overcurrent protection (OCP), undervoltage lockout (UVLO), thermal shutdown, and overvoltage protection (OVP), ensuring that the connected load is protected in the event of a fault.

For design flexibility, the MAX17602ASA+ provides an adjustable output voltage from 0.9V up to 90% of the input voltage, which can be set using external resistors. This allows designers to tailor the output voltage to the specific needs of their application without the need for additional components.

The MAX17602ASA+ is available in a compact 8-pin SOIC package, making it a space-saving solution for space-constrained applications. With its combination of high efficiency, robust protection features, and design flexibility, the MAX17602ASA+ is an excellent choice for a wide array of power conversion needs.
