Maxim Integrated MAX828EUK-TG069 Voltage Converter

The MAX828EUK-TG069 from Maxim Integrated is a high-efficiency, low-power, compact DC-DC converter designed to meet the needs of a wide range of electronic applications. This voltage converter is part of Maxim's well-regarded charge pump or switched-capacitor voltage converters that offer a simple and efficient way to invert input voltages, making it an ideal choice for battery-powered devices where power conservation is critical.

With its ability to invert a positive voltage in the range of +1.5V to +5.5V to the corresponding negative voltage, the MAX828EUK-TG069 is particularly suitable for small, portable devices such as handheld medical equipment, mobile phones, and other portable consumer electronics. Its small SOT23-5 package makes it a perfect fit for space-constrained applications, providing designers with a compact power solution without sacrificing performance.

Key features of the MAX828EUK-TG069 include its no-load quiescent current of only 15µA, which extends battery life by minimizing power consumption when the device is in standby mode. The converter also boasts a high power efficiency, which reduces heat generation and allows for longer operation times between charges. Additionally, its operating temperature range of -40°C to +85°C ensures reliable performance across a wide range of environmental conditions.

The simplicity of the MAX828EUK-TG069's design allows for minimal external components, requiring only two capacitors to complete the circuit. This not only saves on board space but also reduces the overall cost of the power supply design. Furthermore, the device's 500kHz fixed-frequency operation minimizes the size of external components while avoiding critical noise-sensitive frequency bands, making it an excellent choice for noise-sensitive applications.

Overall, the Maxim Integrated MAX828EUK-TG069 voltage converter is a robust and reliable solution for designers looking to add a negative voltage rail to their projects with minimal impact on space and power budget. Its ease of use, efficiency, and compact size make it a versatile component for a multitude of applications.
