L4931 VLDO Regulator Issue
Posted on March 28, 2013 at 16:31I am using the L4931 VLDO regulator in my circuit, to regulate form 12.5VDC input to 3.3VDCThe part number that I am using is the L4931ABDT33 with the correct input and output capacitors as stated in the datasheet te...
L6480 Mosfet driver
Posted on March 18, 2013 at 23:51What is the smallest RDS on value that will work with the L6480? How do I set the phase current to 2.3 amps?
L6480 Eval
Posted on March 06, 2013 at 16:20I am trying to get the L6480 Demo board communicating with the L6480 Evaluation software using the the STEVAL-PCC009V2. I have tried in Windows 7 and Windows XP and was able to get the driver for the PCC0009V2 loade...
Stepper motor controller with L6506 and L298
Posted on October 01, 2012 at 11:52Hi, I'm new to this forum, because I really need some help designing a driver board for a stepper motor. The motor has to phases, 1A per phase, 8.6V and will be controlled over A+/- and B+/- (bipolar). The board wi...
L6926 - Thermal Shutdown
Posted on August 17, 2012 at 16:05Hi, I have tested over 20+ boards that was designed to take L6926 regulators and find that some of the regulators abruptly go into thermal shutdown mode. I think it is thermal shutdown because it tries to spring bac...
LED2000 vs ST1CC40
Posted on February 23, 2013 at 12:58Is there any difference betweem ST1CC40 and LED2000 regulators?I coundn't tell any difference based on datasheet info.
LED2000 circuit parameter measurement
Posted on February 21, 2013 at 12:35I have built up a prototype board of a 2A white LED driver using the LED2000 step down converter with a single LiIon battery as the power source. Everything seems to be working as it should, but I would like to te...
L6470 & Maximum currect limiting
Posted on February 28, 2013 at 11:20Hi, I'm evaluating the L6470 for a project. Going over the datasheet I noticed that the minimum value for 'maximum current limiting' is 375mA. I need to drive a very small stepper (6mm) with 12V power source. Acco...
Frequency pwm with stm3210b
Posted on December 05, 2012 at 10:23Hello, I'm working with stm3210b-eval, I'm doing the following procedures : 1 : I generate with st Workench files in systems drives and params 2 : I compile with IAR But, in ST workench, the frequency params is 16...
PID controller
Posted on January 30, 2013 at 19:06I want to use the pid function in the library arm math. if I project the PID controller in the domain S as I can find the constants KI, KP, and KD in the discrete-time to give the PID controller?thanks for your he...
