The temperature-controlled PWM boost converter in Figure 1 allows operation of a 12V brushless dc fan from a 5V supply. The circuit is based on IC 1, a single-chip ...

I have a Darlington transistor to keep cool. It is a lovely chunky TIP147 in a TO247 package, attached to a PC heatsink (£6 from ebay) to get the heat out. PC heatsinks are great as they often include ...

Noctua has today announced its NA-VC1 24V DC to 12V DC step-down voltage converter allowing for users to run standard 12V fans in 24V environments such as 3D printers or industrial and automotive ...

This circuit idea is certainly not new, but when it comes to making a trade-of between using a small, short-circuit proof transformer or a capacitive voltage divider (directly from 230 V mains voltage ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...

Diodes Inc.has announced the introduction of a pair of all-in-one single-phase 12 V fan motor drivers for low to medium voltage brushless DC fan control in consumer, home appliance, industrial and ...

Serial would mean the +V of one fan is connected to the Gnd of the next, and assuming each fan is identical, each fan would only get a fraction of 12V (2 fans @ 6V each might make them spin slowly, ...
