应用须知
- LMZ35003 Protects Against 60-V Line TransientsPDF, 27 Kb, 档案已发布: Jun 18, 2015
The LMZ35003, wide input voltage, 2.5-A Simple SwitcherВ® power module is designed for typicaloperating input voltages of 7 V to 50 V. However, with a 65-V absolute maximum input voltage rating, theLMZ35003 can be used in applications where the input voltage exceeds 50 V during line transients. The 7V to 50 V operating input voltage range of the LMZ35003 is recommended for the best performanc - LMZ35003 Parallel OperationPDF, 218 Kb, 档案已发布: May 28, 2014
The LMZ35003 is a 7-V to 50-V input, 2.5-A output, integrated power module which integrates a DC/DCconverter, shielded inductor and passives in a low-profile, QFN package. For applications requiring greaterthan 2.5 A, it is possible to parallel multiple LMZ35003 devices by following the recommendations in thispaper. - Power Module MSL RatingsPDF, 137 Kb, 档案已发布: Jan 20, 2017

- AN-1520 A Guide to Board Layout for Best Thermal Resistance for Exposed Packages (Rev. B)PDF, 9.2 Mb, 修订版: B, 档案已发布: Apr 23, 2013
This thermal application report provides guidelines for the optimal board layout to achieve the best thermalresistance for exposed packages. The thermal resistance between junction-to-ambient (ОёJA) is highlydependent on the PCB (Printed Circuit Board) design factors. This becomes more critical for packageshaving very low thermal resistance between junction-to-case such as exposed pad TSSOP - AN-2155 Layout Tips for EMI Reduction in DC/ DC Converters (Rev.

Electromagnetic Interference (EMI) is an unwanted effect between two electrical systems as a result ofeither electromagnetic radiation or electromagnetic conduction. EMI is the major adverse effect caused bythe application of switch-mode power supplies (SMPS). In switching power supplies EMI noise isunavoidable due to the switching actions of the semiconductor devices and resulting disconti - QFN and SON PCB Attachment (Rev.
