EVALUATION KIT AVAILABLE  
MAX5096/MAX5097  
40V, 600mA Buck Converters with Low-  
Quiescent-Current Linear Regulator Mode  
General Description  
Features  
● High-Efficiency Switcher Mode (Buck Mode) or Low-  
Quiescent-Current Linear Regulator (LDO Mode)  
Operation  
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-  
● Wide Operating Input Voltage Range  
• +5V to +40V Buck Mode  
• +4V to +40V LDO Mode  
quiescent-current (I ) LDO mode of operation at light  
● Fixed 3.3V or 5V and Adjustable (1.24V to 11V)  
Q
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.  
Output Voltage Versions  
● 6μA (typ) Shutdown Current  
● Fixed 135kHz or 330kHz Switching Frequency  
● External Frequency Synchronization  
● Programmable Soft-Start  
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.  
● Integrated Microprocessor-Reset (RESET) Circuit  
with Programmable Timeout Period  
● Thermal and Short-Circuit Protection  
● -40°C to +125°C Automotive Temperature Range  
● Thermally Enhanced Package Dissipates 2.6W at  
T = +70°C (16-Pin TQFN) and 1.7W at T = +70°C

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.
