The UC2610N requires careful layout and placement to ensure proper operation. TI recommends placing the device near the input capacitors, using a solid ground plane, and keeping the input and output traces short and wide. A 4-layer PCB with a dedicated power plane is also recommended.
The input capacitors should be selected based on the input voltage, current, and frequency. TI recommends using low-ESR capacitors with a voltage rating of at least 1.5 times the maximum input voltage. The capacitance value should be chosen to ensure that the input ripple voltage is within the specified limits.
The UC2610N can deliver up to 1A of output current, but this is dependent on the input voltage, output voltage, and thermal conditions. TI recommends derating the output current based on the ambient temperature and using a heat sink if necessary.
The UC2610N has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCP pin and ground. The value of the resistor determines the overcurrent threshold. TI recommends using a 1kΩ resistor for a 1A overcurrent threshold.
The EN pin is an enable input that allows the user to turn the device on and off. When the EN pin is high, the device is enabled, and when it is low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device during shutdown.
