Maxim Integrated's MAX17243ETPA+T Boost Converter

The MAX17243ETPA+T is a high-efficiency, synchronous step-up DC-DC converter from Maxim Integrated, designed to provide a compact and reliable power solution for a wide range of applications. This versatile component is capable of delivering a continuous output current up to 2A with an input voltage range of 3.5V to 36V, making it ideal for battery-powered devices, industrial equipment, and portable electronics that require a stable and efficient power supply.

Featuring a fixed 400kHz switching frequency, the MAX17243ETPA+T allows for a balance between efficiency and the size of external components. This makes it possible to use smaller inductors and capacitors, reducing the overall footprint and cost of the power supply design. The device also includes an internal compensation network, which minimizes the number of external components required and simplifies the design process.

The MAX17243ETPA+T incorporates a range of protective features to ensure the safety and longevity of the end application. These features include over-voltage protection, under-voltage lockout, thermal shutdown, and short-circuit protection. The device's True Shutdown™ mode disconnects the output from the input with no forward or reverse current, providing additional safety for sensitive downstream components.

For design flexibility, the MAX17243ETPA+T offers a programmable soft-start function that allows designers to control the inrush current during startup, reducing stress on the input power source. Its small 16-pin TQFN-EP package is suitable for space-constrained applications, and its extended temperature range of -40°C to +125°C ensures reliable operation in harsh environments.

Maxim Integrated's commitment to quality and performance is evident in the MAX17243ETPA+T boost converter, which is designed to meet the requirements of a broad array of power management challenges. With its high efficiency, robust protection features, and compact size, this component is an excellent choice for engineers looking to enhance the performance and reliability of their power supply designs.
