Frequently asked questions
What is the price of L5991D Current-Mode Switching PWM Controller in Egypt?
L5991D Current-Mode Switching PWM Controller currently costs 217 EGP in Egypt.
Where can I buy L5991D Current-Mode Switching PWM Controller in Egypt?
L5991D Current-Mode Switching PWM Controller is available from UGE. Compare the offers above to find the best price.
What is the L5991D used for?
It is the control IC of a switch-mode power supply. It drives the power switch with PWM based on feedback from the output, so it is used in regulator and converter designs rather than as a standalone part.
Can I use it to drive a DC motor?
No. The L5991D is a power-supply controller, not a motor driver. A motor needs a dedicated motor driver IC or module that can handle its current and direction control.
