LM27403EVM-POL600

The LM27403EVM-POL600 is an evaluation module for LM27403 device. The LM27403 is a feature rich, easy to use, synchronous buck controller offering exceptional levels of integration and performance for superior efficiency in high power density, point of load (POL) DC to DC regulator solutions. The LM27403EVM-POL600 is a 600KHz synchronous buck DC to DC regulator showcasing high power density and high efficiency. A 20mm x 15mm module on a single side PCB uses a power block MOSFET. Accurate overcurrent protection is available by leveraging the inductor's sub mohm DCR and MOSFET package resistance. A 2N3904 BJT senses temperature to compensate for the copper temperature coefficient and to provide a thermal shutdown function based on a desired temperature setpoint. Precision enable, power supply tracking, open drain power good indicator, remote sense and synchronization features are also provided. The module is solder mounted directly on the motherboard for maximum thermal performance.
