40V, 600mA Buck Converters with Low-  
Quiescent-Current Linear Regulator Mode  
General Description  
Features  
♦ High-Efficiency Switcher Mode (Buck Mode) or  
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-  
Low-Quiescent-Current Linear Regulator  
(LDO Mode) Operation  
♦ Wide Operating Input Voltage Range  
+5V to +40V Buck Mode  
+4V to +40V LDO Mode  
♦ Fixed 3.3V or 5V and Adjustable (1.24V to 11V)  
escent-current (I ) LDO mode of operation at light load.  
Q
Output Voltage Versions  
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.  
♦ 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)

Ordering Information  
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 quiescent 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 over-  
load, short-circuit and thermal shutdown protections.  
The MAX5096/MAX5097 operate over the -40°C to  
+125°C automotive temperature range and are avail-  
able in thermally enhanced 20-pin TSSOP or 16-pin  
TQFN packages.
