Maxim Integrated MAX1835EUT-T Step-Down Converter

The MAX1835EUT-T is a high-efficiency, compact, synchronous step-down DC-DC converter manufactured by Maxim Integrated. Designed to deliver a continuous output current of up to 600mA, this converter is ideal for portable applications where space and power efficiency are critical. The MAX1835EUT-T operates over a wide input voltage range from 2.6V to 5.5V, making it versatile for various battery-powered devices, including single-cell Li-ion or three-cell NiMH/NiCd powered electronics.

One of the key features of the MAX1835EUT-T is its high efficiency, which can reach up to 96%, thereby minimizing power loss and extending battery life. It achieves this remarkable efficiency through its synchronous rectification and low quiescent current. The device also incorporates a 1.2MHz fixed-frequency PWM mode for better noise immunity and filter size reduction, which is particularly beneficial in space-constrained applications.

The MAX1835EUT-T comes in a tiny 6-pin SOT23 package, which is highly advantageous for portable devices where PCB real estate is at a premium. Its small size does not compromise its performance, as it includes features such as soft-start to reduce inrush current and provide a controlled startup, and a power-save mode that reduces the switching frequency under light loads to improve efficiency further.

To ensure device protection, the MAX1835EUT-T includes a range of safety features. Overcurrent protection guards the device against excessive currents, while thermal overload protection ensures the converter operates within safe temperature limits. Additionally, the device has a low-battery detector to signal when the input voltage falls below a preset threshold, helping to prevent deep discharge of the battery.

Whether you're designing power management systems for handheld computers, smartphones, PDAs, or other portable devices, the Maxim Integrated MAX1835EUT-T offers a blend of high efficiency, compact size, and robust protection features that make it an excellent choice for your next project.
