40V, 600mA Buck Converters with Low-
Quiescent-Current Linear Regulator Mode
General Description
The MAX5096/MAX5097 easy-to-use, Dual Mode ?,
DC-DC converters operate as LDO (low dropout) or
switch-mode buck converters. At a high output load,
the converters operate as high-efficiency pulse-width-
modulated (PWM) switch-mode converters and reduce
the power dissipation. The devices switch to a low-qui-
escent-current (I Q ) LDO mode of operation at light load.
During the key-off condition, the system’s microcon-
troller drives the LDO/ BUCK input on the fly and forces
the MAX5096/MAX5097 into LDO Mode, thereby reduc-
ing the quiescent current significantly.
In Buck Mode, the MAX5096/MAX5097 operate from a 5V
to 40V input voltage range and deliver up to 600mA of
load current with excellent load and line regulation. The
fixed-switching frequency versions of 135kHz and
330kHz are available. The MAX5096/MAX5097 DC-DC
internal oscillator can be synchronized to an external
clock. External compensation and a current-mode control
scheme make it easy to design with.
In LDO Mode, the MAX5096/MAX5097 operate from a
4V to 40V input voltage. The LDO Mode operation is

The MAX5096/MAX5097 feature an enable input that
shuts down the device, reducing the current consump-
tion to 6μA (typ). Additional features include a power-on
reset output with a capacitor-adjustable timeout period,
programmable soft-start, output tracking, output over-
load, short-circuit and thermal shutdown protections.
