Rainbow Electronics MAX607 - Manual

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 pro-
vide a ±4% accurate output that is preset to 5V or 12V,
or adjustable from V
IN 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
2 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
2 , 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.
