Wide-Input 0.6V Shunt Regulators for  
Isolated DC-to-DC Converters  
General Description  
Features  
The MAX8515A/MAX8515 shunt regulators simplify the  
design of voltage regulation and overvoltage protection  
(OVP) functions in high-accuracy isolated DC-to-DC con-  
verters with output voltages as low as 0.6V. The devices  
have supply voltage and feedback inputs separated from  
the output shunt stage, and can operate directly from the  
DC-to-DC converter output stage when the output voltage  
is 1.8V to 18V. Alternately, the MAX8515A/MAX8515 input  
stage can be biased from an unregulated 1.7V to 28V  
supply, independent of DC-to-DC converter output volt-  
age. The MAX8515A/MAX8515 shunts 20mA when the  
output voltage is as low as 0.2V.

The MAX8515A features an initial output accuracy of  
0.5% at +25°C and 1% from -40°C to +85°C and provides  
the output voltage regulation function for isolated DC-to-  
DC converters. The MAX8515 features initial output  
accuracy of 1% at +25°C and 1.8% from -40°C to +85°C  
and can provide an output OVP function for isolated DC-  
to-DC converters. High open-loop bandwidth allows  
design of high-bandwidth DC-to-DC converters.

Low-cost, low-dropout linear regulators can be designed  
with the MAX8515A/MAX8515 and an external NPN tran-  
sistor for cost-conscious applications that do not require  
overcurrent, short-circuit, or overtemperature protection.

The MAX8515/MAX8515A are available in space-saving  
5-pin SC70 and SOT23 packages and are specified over  
the -40°C to +85°C extended temperature range. An eval-  
uation kit is available to speed designs.
