Posted on December 18, 2014 at 17:57Hi,does anyone know when the EVAL6480H-DISC will be available in the UK? Also will it be cheaper than the EVAL6480H evaluation board?Thanks in advance,Howard Smith #eval6480h #eval6480h-disc #l6480

L6591 issue

Hi at everyone,I designed a open loop dc/ac converter, but I met a big problem. The high side output did'nt work correctly over the 40V of Vhv. Over that value the output goes out derivates and the resistance from pin 14 and pin 13 is 5ohm. Aflter a ...

Choosing a reliable DC / DC converter to power the controller (12V / 5V)

Hi!I design a board on which there will be several microcontrollers (STM32 and ATMEGA328), 12V comes on the board and I need to lower this voltage to 5V. In addition to the controllers, I will power a few more sensors and LEDs.I am trying to find a r...

STPM32 Power meter with load relays on both mains lines

Hi, I'm trying to build a power meter that has the ability to switch on and off the attached load.The power supply for the design is created using Viper26LD in buck mode, the processor used to control the design is STM32L051. The entire design analog...

Converts DC-DC PV in series

Hi, I have questions about how serial DC-DC converters work for photovoltaic systems. For, the current in the output tends to be different due to MPPT, which would be several sources of current in series. I read the manual that explains the SPV1020, ...

Which footprint do we need to consider for STL6P3LLH6? Whether its Type C or Type F?

Could you please let me know, which land pattern do we need to consider for  PowerFLAT 3.3 x 3.3 package,for STL6P3LLH6? Whether we need to consider  Type C or Type F package? The data sheet doesn't clearly say which is defined by what and neither do...

L6480H Stall Detection - Does It Really Work?

I'm trying to evaluate if the L6480H stall detection actually works. We have been using the L6470H and we proved that stall detection with that chip did NOT work properly.I bought the EVAL6480H and STEVAL-PC0009V2 boards with the hope that I could pr...

L4970a Output Oscillates

Posted on March 04, 2014 at 09:46I need the following: 24V vehicle input. Allow for 28V. 13.8V @ 10A output. I used an L4970a. My circuit delivers the load, no problem.On initial switch on with no load, the output is stable. When I place a load up t...
