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.
