According to the datasheet,. There are 2 graphs of the Shutdown Threshold vs Temperature. And an LT3845 lt3845 high voltage synchronous step- down converters, may be a good. and the regulation range of a buck- boost topology. The UCx84x series of control integrated circuits provide the features that are necessary to implement off- line DC- to- DC fixed- frequency current- mode control schemes with a minimum number of external components. The LT3845 is a high voltage current mode controller used for medium to high power, synchronous high efficiency supplies.

My doubt pertains to the SHDN pin on the IC. The datasheet is - here. LT3840 Wide Input lt3845 Range Synchronous Regulator Controller Components datasheet pdf data sheet FREE from Datasheet4U. I lt3845 am using the LT3845 to obtain 1. 3V to turn the IC on. In the real world everything will heat up everything else. You do need lt3845 to individually analyse the losses in each part. Lt3845 datasheet. LT3845 SHDN pin behaviour. Remember those datasheet ratings are probably for 25' C ambient temperature, with individual infinite sheets of copper allocated to each part. In the datasheet the minimum start voltage ( see page 3 second parameter) is listed as 7. com Datasheet ( data sheet) search for integrated circuits ( ic) capacitors, semiconductors , transistors , other electronic components such as resistors diodes. Now, lt3845 the SHDN threshold varies with respect to Temperature. From the formula. The SHDN pin is connected to the Vcc via a voltage divider and requires approx 1.
It offers a wide 4V to 60V input range ( 7. I can' t predict which part is making the * most* heat ( at this lt3845 time of night).
