@pradeep.g.belchada:
How can I do it? The circuit output should maintain constant voltage instead of current.
@crutschow:
“What you show is a constant voltage output regulator, not a constant current.”
Yes, the main source is constant current and desired output is regulated dc voltage...
Hi all,
In your opinion is it possible to use a constant current source (i.e. LED Driver) as a digital circuit power supply (like attached schematic)? current source specification: Pout=3W, Isc=200 mA, Voc=20v and the desired regulated voltage is 5V, 100mA.
Thank in Advance,

Hi all,
In your opinion why in this AN they did not use freewheeling diodes for MOSFETs?
**broken link removed**
Is it because of body diodes of MOSFETs or actively freewheeling by brake state?

Hi all,
In your opinion why ARM microcontrollers (like LPC2000 and AT91SAM7) GPIO pins are spreaded and are not aligned like 8-bit microcontrollers? how can I overcome this problem with minimum overhead?
Thank in advance,
Reza
WHY PIC
I think Atmel has rejected Microchip 2.3 billion $ suggestion.
Added after 1 minutes:
AVR's architecture is very interesting and powerful but Microchip documents and supports is better.
USART question
Hi dear friends,
I am interested to know why a character must be framed by start and stop bits in USART's synchronous mode, despite the receiver can be synchronized with transmitter by an external clock line.
Thank in advance,
Reza
Transistor as a switch
Hi dear friends,
In your opinion what's the best configuration of BJT to driving LEDs (DotMatrix, big 7-segments, …) ?
Why common-collector is not suitable for switching heavy loads?
Is there any AN or reference to study more about this subject?
Regards,
Reza
spi termination
Hi all,
I need to use SPI bus on a big Printed Circuit Board (width: 70 cm). Near master microcontroller, there is a SPI DataFlash chip which must be accessed by full speed of AVR's SCK line (8 MHz).
Now I routing PCB and I am worry about refection on bus when master accessing...
Re: I²C in OSI Model
Thank you CMOS, I think so.
In your opinion the term "Address Packet" is correct about I2C bus? (See attached image which is from AVR manual)
