Where can I buy UC3844 Current-Mode PWM Controller IC DIP-8 in Egypt?
UC3844 Current-Mode PWM Controller IC DIP-8 is available from Makers Electronics. Compare the offers above to find the best price.
How do I connect the current-sense pin?
Place a small sense resistor in the source path of the external MOSFET and connect the voltage across it to the current-sense pin, through a small RC filter. This lets the IC limit peak switch current cycle by cycle.
What supply voltage does it need to start?
The typical start threshold is 16V and the lockout turns it off near 10V. Power it from a supply that rises above the start threshold, and check the datasheet for the exact limits and the maximum supply rating.
