The new MAX13256 from Maxim is an H-bridge transformer driver with a wide input voltage range for isolated power supplies. It is designed to allow engineers to quickly design a highly efficient (up to 90%) isolated DC-DC converter.
The chip drives a transformer’s primary coil with up to 300 mA of current from an 8 V to 36 V d.c. supply which can deliver up to 10 W of isolated power. Users can choose their own transformer winding ratio which defines the output voltage, thus allowing the selection of virtually any isolated output voltage. This robust supply range eliminates external voltage regulation. Integrated protection features prevent system-level failures. These capabilities make the driver suitable for creating isolated power supplies in smart grid metering applications and industrial and medical equipment.
Smart grid applications utilising wired interface communications require isolated power to protect against high-voltage mains that can damage both the installer and the power meter’s internal electronics. The isolated power is typically generated with a transformer and discrete components which increase the solution size and add cost. The MAX13256 drives the transformer that acts as the additional form of isolation from high-voltage mains.
A smart grid has different requirements for input voltage and output power that vary based on the type of interface used to communicate with the smart meter. The MAX13256’s 8 V to 36 V input voltage range addresses these diverse power supply input requirements. It also eliminates external voltage regulation and enables flexible transformer options to satisfy a wide range of power output requirements.
Adjustable current limiting allows indirect limiting of secondary side load currents. An over-current limit is set by an external resistor over the 215 mA to 650 mA range. An active-low FAULT output asserts when the device detects an over-temperature or over-current condition.
