MAX606 - Step-Up DC-DC Converters

General Description

The MAX606/MAX607 are the smallest CMOS, step-up DC-DC converters available for flash memory and PC (PCMCIA) cards.

They switch at up to 1MHz, permitting the entire circuit to fit in 0.25in 2 , yet remain under 1.35mm high to fit Type 1, 2, and 3 card standards.

These devices operate from a 3V to 5.

Key Features

  • include 1µA logic-controlled shutdown and usercontrolled soft-start to minimize inrush currents. The MAX606/MAX607 come in 8-pin µMAX and SO packages. The µMAX package uses half the board area of a standard 8-pin SO and has a maximum height of just 1.11mm.

19-0459; Rev 1; 1/99 Low-Profile, 5V/12V or Adjustable, Step-Up DC-DC Converters for Flash Memory/PCMCIA Cards General Description The MAX606/MAX607 are the smallest CMOS, step-up DC-DC converters available for flash memory and PC (PCMCIA) cards. They switch at up to 1MHz, permitting the entire circuit to fit in 0.25in 2 , yet remain under 1.35mm high to fit Type 1, 2, and 3 card standards. These devices operate from a 3V to 5.5V input and provide a ±4% accurate output that is preset to 5V or 12V, or adjustable from VIN to 12.5V. They can provide up to 180mA of output current at 5V. The MAX606 switches at up to 1MHz and fits Type 1 (thinnest standard) flash memory and PCMCIA cards. It uses a thin, 1.19mm high, 5µH inductor and small, 0.68µF output capacitors. The entire circuit fits in 0.
