Senses current levels to prevent damage during a short circuit. Common Troubleshooting and Repair
This IC is widely utilized in the power supply boards (PSUs) of several popular HP and Canon laser printer models:
SIP 15-pin (Single In-line Package), which allows for vertical mounting to save PCB space.
Because it is a 15-pin SIP component, replacement requires careful desoldering of the old chip and ensuring the new chip is securely soldered to avoid thermal issues or cold joints.
Features circuitry to prevent voltage drops or overload, ensuring stable power delivery to sensitive printer electronics. Typical Applications
The supply voltage for the IC's internal control circuitry.
PWM controller with a built-in power switch for DC power board supplies.
