The MAX1797EUA from Analog Devices is a high-efficiency, step-up DC-DC converter designed for portable hand-held devices. It 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. The device also includes LX-damping circuitry for reduced EMI.
This converter operates with an input voltage range of +0.7V to VOUT, where VOUT can be set from +2V to +5.5V, with guaranteed startup from +0.85V. It offers a preset, pin-selectable 5V or 3.3V output, or can be adjusted to other voltages using two external resistors. The MAX1797EUA has a current limit of 1A and operates at a frequency of 500kHz.
Key electrical characteristics include a 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. The operating temperature range is -40°C to +85°C.
Applications for the MAX1797EUA include portable digital audio players, PDAs/palmtops, wireless handsets, and portable terminals. Its surface mountable design and small package size make it suitable for space-constrained applications.
