MAX1674EUA is a flexible, programmable DC-DC step-up (boost) switching regulator designed with a wide input voltage range, high efficiency, and wide output voltage range. It is suitable for applications such as automotive and industrial control, telecom, and networking. This device offers full protection against overvoltage and overcurrent conditions, preventing power supply failures and overheating.The MAX1674EUA is specifically designed for multi-cell Li-ion/Li-polymer battery powered systems. It switches at a fixed frequency and uses a core-regulated architecture that can cope with wide input voltage variations. The device is also optimized for battery backup applications and can operate up to 6V input. The MAX1674EUA incorporates an adjustable voltage (AV) feature, which allows the input voltage to be adjusted within a range of 1.3V to 5.5V. It is designed to switch at adjustable frequencies from 1kHz to 600kHz. It also provides an independent output voltage range from 0.9V to 4V.The MAX1674EUA employs current mode control with synchronous rectification for high efficiency operation. To provide full protection for both the device and the system, it includes overvoltage, overcurrent, and thermal shutdown features.The device includes two integrated MOSFETs capable of operating at up to 5A peaks. The integrated MOSFETs are optimized for higher efficiency, lower on-resistance, and lower heat dissipation.The MAX1674EUA is available in a small TDFN 4x4mm package and is fully specified over the -40°C to +85°C temperature range.
