LM27403EVM-POL600
概述
LM27403EVM-POL600 is a 600-kHz synchronous buck dc-dc regulator showcasing high power density and high efficiency. A 20 mm x 15 mm module on a single-side PCB uses a power block MOSFET from TI. 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 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.
