MAXIM INTEGRATED / ANALOG DEVICES MAX1677EEE Boost Converter

The MAX1677EEE+ is a compact, high-efficiency dual-output boost converter designed for portable devices requiring two regulated power supplies, typically for logic and LCD displays. It operates with input voltages as low as 0.7V, making it compatible with 1 to 3-cell alkaline, NiCd, NiMH, or lithium-ion batteries. The device features an integrated FET, consumes only 20µA in low-power mode, and can supply up to 350mA at either 3.3V or an adjustable voltage between 2.5V and 5.5V. With on-chip synchronous rectification, it achieves efficiencies up to 95%. Its 300kHz PWM operation is suitable for low-noise applications, such as wireless devices. The supply voltage range is 0.7V to 5.5V, with a temperature operating range from -40°C to 85°C. It can handle LCD bias currents up to ±28V with programmable current limits, a shutdown current of 1µA, and includes a low battery comparator. Ideal for power management in portable devices, it is currently experiencing extended lead times due to high market demand.
