The MAX1795EUA+ is a high-efficiency, step-up DC-DC converter designed for small portable hand-held devices. It features Maxim's True Shutdown circuitry, which fully disconnects the output from the input in shutdown, improving efficiency and eliminating the need for an external Schottky diode. The device also includes proprietary LX-damping circuitry for reduced EMI in noise-sensitive applications.
With an input voltage range starting at 0.7V and a guaranteed startup from 0.85V, the MAX1795EUA+ is suitable for battery-powered applications. The output voltage can be set from 2V to 5.5V, either through preset 5V or 3.3V options or by using two external resistors for adjustable output. This specific model has a current limit of 200mA.
The converter operates at a switching frequency of 500kHz and achieves over 95% efficiency. It consumes only 25μA of quiescent supply current and 2μA in shutdown mode. The device is housed in a compact, 8-pin μMAX package, measuring only 1.09mm tall.
Applications for the MAX1795EUA+ include portable digital audio players, PDAs/palmtops, wireless handsets, and portable terminals. The integrated LBI/LBO comparator remains active even when the DC-DC converter is in shutdown, providing additional in-system flexibility.
