Description

The thing to remember about buck regulators is; if the series switch transistor fails SC - it dumps the full unregulated voltage into the load. Part of me really wants to just go with an older converter with an external through hole FET and stick a huge heatsink on it and just take a silly safety margin to avoid wasting much time on a low volume project. The switch node of a switching regulator or power converter circuit is a critical conduction path that requires special attention when designing the PCB layout. The maximum output voltage refers to the dynamic area beyond which the output is saturated in the positive or negative direction, and is limited according to the load resistance value. I used this converter to build a 12 volt driven field charger that has four 5 volt channels allowing me to charge 5 drone batteries at once.

Is it a case that EN floats, and a pullup resistor is used on the board to allow usage without any input on the EN pin?

I'm tempted to just use two buck regulators to get the 12, but what might be more fun is sticking a second winding on the inductor.

The extract from the datasheet I have quoted above says that if the EN pin is left to float, it is pulled up internally. TI also produces TI digital light processing (DLP) technology and education technology products including calculators, microcontrollers, and multi-core processors. When I received them, they were set to 12v output, which had to adjusted using a miniature trimmer on the board. According to my calculations, that would give me well over 2,000 days of standby time on a pair of 18650 Cells in series (7.If you're going to use a crowbar SCR - you have to include a diode so it only shorts the charger and NOT the battery. Synchronous rectification is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT).
