EVALUATION KIT AVAILABLE  
MAX5098A  
Dual 2.2MHz Buck or Boost Converter  
with 80V Load-Dump Protection  
General Description  
Features  
The MAX5098A is  
a dual-output, high-switching-  
● Wide 4.5V to 5.5V or 5.2V to 19V Input Voltage  
frequency DC-DC converter with integrated n-channel  
switches that can be used either in high-side or low-  
side configuration. Each output can be configured either  
as a buck converter or a boost converter. In the buck  
configuration, this device delivers up to 2A from  
converter 1 and 1A from converter 2. The MAX5098A also  
integrates a load-dump protection circuitry that is capable  
of handling load-dump transients up to 80V for industrial  
applications. The load-dump protection circuit utilizes  
an internal charge pump to drive the gate of an external  
n-channel MOSFET. When an overvoltage or load-dump  
condition occurs, the series protection MOSFET absorbs  
the high-voltage transient to prevent damage to lower-  
voltage components.  
Range (with Up to 80V Load-Dump Protection)  
● Dual-Output DC-DC Converter with Integrated Power

● Each Output Configurable in Buck or Boost Mode  
● Adjustable Outputs from 0.8V to 0.85V Buck

IN  
Configuration)  
● I  
and I  
of 2A and 1A (Respectively) in  
OUT1  
OUT2  
Buck Configuration  
● Switching Frequency Programmable from 200kHz to  
2.2MHz  
● Synchronization Input (SYNC)  
The DC-DC converters operate over a wide operating  
voltage range from 4.5V to 19V. The MAX5098A operates  
180° out-of-phase with an adjustable switching frequency  
to minimize external components while allowing the ability  
to make trade-offs between the size, efficiency, and cost.  
● Clock Output (CKO) for Four-Phase Master-Slave  
Operation  
● Individual Converter Enable Input and Power-Good  
Output  
This device utilizes voltage-mode control for stable  
operation and external compensation; thus, the loop gain  
is tailored to optimize component selection and transient  
response. This device can be synchronized to an external  
clock fed at the SYNC input. Also, a clock output (CKO)  
allows a master-slave connection of two devices with a  
four-phase synchronized switching sequence. Additional  
features include internal digital soft-start, individual enable  
for each DC-DC regulator (EN1 and EN2), open-drain  
power-good outputs (PGOOD1 and PGOOD2), and a  
shutdown input (ON/OFF).  
● Low-I (7µA) Standby Current (ON/OFF)  
Q
● Internal Digital Soft-Start and Soft-Stop  
● Short-Circuit Protection on Outputs and Maximum  
Duty-Cycle Limit  
● Overvoltage Protection on Outputs with Auto Restart  
● Thermal Shutdown  
● Thermally Enhanced 32-Pin TQFN Package  
Dissipates Up to 2.7W at +70°C  
Ordering Information  
Other features of the MAX5098A include overvolt-  
age protection, short-circuit (hiccup current limit), and  
thermal protection. The MAX5098A is available in  
a thermally enhanced, exposed pad, 5mm x 5mm,  
32-pin TQFN package and is fully specified over the  
-40°C to +125°C temperature range.
