MAX5096/MAX5097

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-

quiescent-current (I

) 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 intended

for a lower output load current of up to 100mA. The quies-

cent current at 100μA load in LDO mode is only 41μA (typ).

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 overload,

short-circuit, and thermal-shutdown protections.

The MAX5096/MAX5097 operate over the -40°C to

+125°C automotive temperature range and are available

in thermally enhanced 20-pin TSSOP or 16-pin TQFN

packages.
