MAXIM INTEGRATED / ANALOG DEVICES MAX1678EUA Battery Boost Converter

The MAX1678EUA+ is a high-efficiency, low-noise, step-up DC-DC converter designed for single-cell to two-cell battery-powered devices. It is packaged in an 8-pin µMAX package with an overall height of 1.1mm. This synchronous rectified boost converter supports input voltages from 0.7V to 5.5V and outputs a preset voltage of 3.3V, which can be adjusted from +2V to +5.5V using two external resistors. It features a low start-up voltage of 0.87V, a quiescent current of just 37µA, and includes a built-in 1Ω N-channel MOSFET switch, a synchronous catch diode, and pulse-frequency modulation control circuitry to optimize efficiency—up to 90% at loads up to 50mA. Additional features include an undervoltage comparator, a power-fail detector, EMI suppression via an inductor damping switch, and a low-power shutdown mode controlled by a logic signal. Suitable for portable power management applications, the device operates within a temperature range of -40°C to 85°C. Note: Due to market demand, lead times may be extended, and delivery dates are subject to change. This product is not eligible for discounts.
