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

, 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 pro-

vide a ±4% accurate output that is preset to 5V or 12V,

or adjustable from V

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

0.25in

and is less than 1.35mm high.

The MAX607 switches at up to 500kHz, fitting Type 2

and 3 cards, as well as hand-held devices where

height requirements are not as critical. It uses less

board area than the MAX606, fitting in 0.16in

, but

requires 2.5mm of height. It also has a lower no-load

supply current than the MAX606.

Both devices use a unique control scheme that optimizes

efficiency over all input and output voltages. Other fea-

tures include 1µA logic-controlled shutdown and user-

controlled 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.
