TLD55421IVREGEVALTOBO1

TLD55421IVREGEVALTOBO1 is an evaluation platform for the TLD5542-1 as voltage regulator and LED driver. The TLD5542-1 H-Bridge buck-boost DC-DC controller designed for high power, high efficiency automotive application. The H-bridge architecture is among the most efficient buck-boost topologies for high current applications. The TLD5542-1 provides complete control and diagnostics through the SPI interface. The device can be used in microcontroller-less applications, because of the limp home mode. The default configuration is constant current LED driver with 1.5A maximum output current. The output current can be increased up to 6A or more by changing a shunt resistor.

• Constant current (LED) and constant voltage regulation
• SPI for diagnostics and control
• Limp home function (fail-safe mode)
• EMC optimized device: spread spectrum
