The LM27403EVM-POL600 Module, which is a 600-kHz synchronous buck DC-DC supply showcasing high power density and high efficiency with the TI NexFET Power Block. This board is extremely small (20 mm x 15 mm) on a single-side PCB. Accurate overcurrent protection is available by leveraging the inductor’s sub-mΩ 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 set-point. 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 and can be very useful for showing an end application to a customer.
