2Ω Dynamic Output Impedance o Space-Saving 5-Pin SC70 or SOT23 Packages MAX8515A/MAX8515 The MAX8515A/MAX8515 shunt regulators simplify the design of voltage regulation and overvoltage protection (OVP) functions in high-accuracy isolated DC-to-DC converters 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 voltage.
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-toDC 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 DCto-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 transistor 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.
