MAX762EPA+ High-Efficiency, Step-Up DC-DC Converter

The MAX762EPA+ is a high-performance, step-up DC-DC converter from Maxim Integrated, designed to provide a compact and efficient power supply solution for a variety of applications. This integrated circuit is capable of delivering a fixed or adjustable output voltage from a lower voltage input, making it ideal for battery-powered devices, as well as for boosting the voltage in systems that require higher operating voltages.

Constructed with a high-frequency, pulse-width modulation (PWM) control scheme, the MAX762EPA+ ensures stable and efficient operation even at light loads. Its ability to operate at switching frequencies up to 300kHz allows the use of small, low-cost inductors and capacitors, reducing the overall footprint and bill of materials for the power supply design.

The device features a wide input voltage range from 2V to 16.5V, accommodating a variety of power sources including single-cell batteries. The output voltage can be set from 2.5V up to 16.5V, which provides the flexibility needed to power different components in a system. Additionally, the MAX762EPA+ offers a high efficiency of up to 87%, minimizing power loss and heat generation within the system.

For protection, the MAX762EPA+ incorporates several features to ensure the longevity and reliability of the application. These include thermal overload protection, which shuts down the device to prevent damage from excessive heat, and a current limit function that protects the device and the load from overcurrent conditions. The device also features a low-battery detector that signals when the input voltage falls below a predefined threshold, allowing for power management and battery conservation strategies.

Available in an 8-pin DIP package, the MAX762EPA+ is designed for easy implementation into a wide range of applications, including portable computers, PDAs, cellular phones, and other portable equipment where efficient power conversion is critical. Its robust design and comprehensive feature set make it an excellent choice for designers looking for a reliable and high-performance step-up converter solution.
