The MAX1797EUA-T from Analog Devices is a high-efficiency, step-up DC-DC converter designed for portable hand-held devices. It offers >95% efficiency and features Maxim's True Shutdown circuitry, which fully disconnects the output from the input in shutdown mode, improving efficiency and eliminating the need for an external Schottky diode.
This device supports an input voltage range of +0.7V to VOUT, with startup guaranteed from +0.85V. The output voltage can be preset to 3.3V or 5V, or adjusted to other voltages between 2V and 5.5V using two external resistors. It provides an output current of 800mA (switch) and operates at a switching frequency of 500kHz.
The MAX1797EUA-T includes a battery monitoring comparator (LBI/LBO) that remains active even when the DC-DC converter is in shutdown. It has a low quiescent supply current of 25μA and a shutdown current of 2μA. The device is available in a compact 8-pin μMAX package, measuring only 1.09mm tall.
Applications include portable digital audio players, PDAs/palmtops, wireless handsets, and portable terminals. The device is suitable for surface mount applications and operates within a temperature range of -40°C to +85°C.
