Maxim Integrated MAX762CS High-Efficiency, Step-Up DC-DC Converters

The MAX762CS from Maxim Integrated is a high-performance, step-up DC-DC converter designed to provide a reliable power solution for applications requiring a higher voltage from a lower voltage source. This versatile component is ideal for portable devices, as it can efficiently increase battery voltage to the levels necessary for various electronic components.

The MAX762CS operates with an input voltage range from 2.7V to 16.5V, which makes it suitable for a wide array of devices, from single-cell lithium-ion batteries to multi-cell alkaline/NiCd/NiMH batteries. It can deliver an adjustable output voltage up to 16.5V or a fixed 5V, 12V, or 15V, which provides flexibility for designers to use it in different configurations depending on the needs of their specific application.

One of the key features of the MAX762CS is its high efficiency, which is achieved through an internal 1.8A switch that operates at a switching frequency of up to 300kHz. This high-frequency operation enables the use of small, low-cost capacitors and inductors, reducing the overall size and cost of the power supply design. Additionally, the device includes a frequency synchronization pin to synchronize multiple converters in a system.

The MAX762CS also incorporates several protective features to ensure safe operation. These include thermal shutdown, cycle-by-cycle current limit, and a soft-start feature that minimizes inrush current during startup. Furthermore, the device's shutdown mode reduces quiescent current to a mere 15µA, which is beneficial for battery-powered applications where conserving power is crucial.

For designers looking for a compact, efficient, and versatile step-up converter, the MAX762CS is an excellent choice. Its high efficiency, wide input voltage range, adjustable output voltage, and protective features make it a robust solution for powering high-voltage circuits from low-voltage sources in portable electronics, LCD bias supplies, and other similar applications.

Maxim Integrated's commitment to quality and performance is evident in the MAX762CS, providing designers with a reliable and efficient power conversion solution that meets the demands of modern electronic devices.
