App note: Surge-proof your industrial sensor

Design solution for a robust and reliable power supply for industrial sensors from Maxim Integrated. Link here Modern industrial sensors must operate reliably in harsh and demanding industrial environments where they are prone to large surge voltages and mechanical stresses. This places considerable demands on the DC power supply that they use. We consider the […]

App note: MC13783 buck and boost inductor sizing

NXP’s app note on calculating inductor sizes using MC13783 PWM controller as example. Link here (PDF) The purpose of this application note is to provide a method of choosing the size of the inductors for the optimized switching regulators versus the current consumption of the application. This will allow to optimize the size and the […]

Building a DC-DC power supply that works

rsdio tipped us to an app note on DC-DC power supplies: This article discusses important considerations when designing a DC-DC power supply. Topics include choosing the right DC-DC converter for the application; MOSFET gate capacitance; high switching frequencies and component size; equations and calculations; selecting peripheral components; component placement and trade-offs; grounding; load and line […]
