Switching Regulator
General Description
Features
Maxim’s MAX630 and MAX4193 CMOS DC-DC regula-
tors are designed for simple, efficient, minimum-size
DC-DC converter circuits in the 5mW to 5W range. The
MAX630 and MAX4193 provide all control and power
handling functions in a compact 8-pin package: a
1.31V bandgap reference, an oscillator, a voltage com-
parator, and a 375mA N-channel output MOSFET. A
comparator is also provided for low-battery detection.
Operating current is only 70μA and is nearly indepen-
dent of output switch current or duty cycle. A logic-level
input shuts down the regulator to less than 1μA quies-
cent current. Low-current operation ensures high effi-

Ordering Information
ciency even in low-power battery-operated systems.
The MAX630 and MAX4193 are compatible with most
battery voltages, operating from 2.0V to 16.5V.
The devices are pin compatible with the Raytheon bipo-
lar circuits, RC4191/2/3, while providing significantly
improved efficiency and low-voltage operation. Maxim
also manufactures the MAX631, MAX632, and MAX633
DC-DC converters, which reduce the external compo-
nent count in fixed-output 5V, 12V, and 15V circuits.
See Table 2 at the end of this data sheet for a summary
of other Maxim DC-DC converters.
