Power management

I can get my L9960T Evaluation board to work!

I am currently working on a project where we would like to use the L9960T and therefore we have ordered a EVAL-L9960T board.We need to use it only as a simple H-bridge without benefiting from the SPI settings and diagnostics capabilties.I have now be...

Designing doubts with SPV1040

I need to charge LiPo battery with solar cell. I found out the SPV1040. But the datasheet doesn't provide enough details, I was unable to find any document to help me, and the eDesignSuite doesn't work. Related documents use it with L6924. Can I simp...

STM32F103 power management

Hello,I m designing a board with a STM32F103. I was wondering about capacitors value. In STM32 documentation, it's written to use 100nf per VDD PIN + one 4.7uF. On the other side, I m using a low dropout regulator :I dont' understand where to place ...

Layout Recommendation for inverting DC-DC Converter MC34063

I am using the MC34063ECD-TR to take 5V and make -12V. I'm using the schematic as recommended in the datasheet for this application (with the exception of using a 100uH inductor instead of a 90uH inductor). It is working nicely electrically - I get...

Can STEVAL_POE002V1 work as 24V source?

I bought the STEVAL_POE002v1. It works fine at 5 V. Now I want to setup a POE with 24V. Can I achieve this with that STEVAL? I would think to change the transformer and to adjust the Feedback-path and perhaps the Fsw. Can you help me with a calculati...

STM6600 VCCLO

The description of the VCCLO pin says it goes low when Vcc is below Vth+.However, the timing diagrams 20 and 21 show VCCLO going low tdebounce after VCC drops below Vth-.Which is correct?

Acoustic Noise L6599

I absolutely do not understand under what conditions and for what reason sometimes during operation of the LLC converter, the power transformer emits audible high-frequency acoustic noise. Some instances work fine, but some make a good audible noise....

is the STSPIN32F0A suitable as a gimbal motor controller without hall sensors(or other sensors)

Im currently looking for a more intelligent replacement driver for our robotics wheels. Currently we use very small BLDC "WITHOUT sensors and it will stay that way" We have typically controlled the BLDC through a "PWM Table array" using 3 PWM chann...
