Figure 1: A digital camera connected to a tablet via a USB-C cable
USB-C and USB-C power delivery raise voltage and power levels. A new reversible connector with tighter pin pitch than that of USB Micro-B, increases the risk of short circuits. This, in conjunction with the ever-increasing complexity of portable devices leads to enhanced ESD, surge and overvoltage protection re

Figure 1. LED lighting controls now serve a key entry point into building automation systems, which uses interconnected networks of software and hardware to monitor and control all the building’s electrical and mechanical systems
The “lighting revolution” is old news now.
Building automation is the new bedrock-shifting event unfolding within the building world now, and it too is being spurred by advancements in LED technology and controls.
The premise that lighting should be independent from other building systems is now antiquate

Lighting has been a commodity market since incandescent light was invented. The Phoebus cartel, formed in 1925 by Osram, GE, Associated Electrical, Philips, and others, controlled the worldwide sale and manufacturing of lamps until it disbanded in 1939 when WWII started. The cartel also set the lifespan of incandescent bu

Figure 1. The 5 V output converter (U1) provides hold-up power for protected load on the 3.3 V output (U2). Note that the pin MODE/SYNC of U1 is left floating, allowing the LTC3649 to enter boost mode
The LTC3649 is a monolithic step-down regulator capable of operating from an input voltage range of 3.1 V to 60 V, and efficiently producing a single resistor-programmable output voltage at up to 4 A of output current. These features alone make it a compelling industrial or automotive supply for output voltages fr
