Switch-Mode Regulator with
+5V to ±12V or ±15V Dual Output
_______________General Description
The MAX742 DC-DC converter is a controller for dual-out-
put power supplies in the 3W to 60W range. Relying on
simple two-terminal inductors rather than transformers, the
MAX742 regulates both outputs independently to within
±4% over all conditions of line voltage, temperature, and
load current.
The MAX742 has high efficiency (up to 92%) over a wide
range of output loading. Two independent PWM current-
____________________________Features
o Specs Guaranteed for In-Circuit Performance
o Load Currents to ±2A
o 4.2V to 10V Input-Voltage Range
o Switches From ±15V to ±12V Under Logic Control
o ±4% Output Tolerance Max Over Temp, Line,
and Load
o 90% Typ Efficiency
mode feedback loops provide tight regulation and opera-
tion free from subharmonic noise. The MAX742 can
operate at 100kHz or 200kHz, so it can be used with small
and lightweight external components. Also ripple and
noise are easy to filter. The MAX742 provides a regulated
output for inputs ranging from 4.2V to 10V (and higher with
additional components).

______________Ordering Information
External power MOSFETs driven directly from the MAX742
are protected by cycle-by-cycle overcurrent sensing. The
MAX742 also features undervoltage lockout, thermal shut-
down, and programmable soft-start.
If 3W of load power or less is needed, refer to the MAX743
data sheet for a device with internal power MOSFETs.
