Texas Instruments provides a recommended PCB layout in the DIR9001IPWRQ1 evaluation module documentation, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The DIR9001IPWRQ1 has a programmable input voltage range, which can be configured using the EN_PIN and VSENSE pins. The device can be configured for different input voltage ranges by adjusting the voltage divider network connected to the VSENSE pin and setting the EN_PIN accordingly. Refer to the datasheet and application notes for specific configuration guidelines.
The DIR9001IPWRQ1 is capable of delivering up to 1.5 A of output current, but this is dependent on the input voltage, output voltage, and thermal conditions. It's essential to ensure the device is properly heatsinked and operated within the recommended operating conditions to achieve the maximum output current.
The DIR9001IPWRQ1 has built-in OCP and SCP features. To implement these features, connect a sense resistor (Rs) between the output pin and the GND pin, and connect the OCP pin to a voltage source (e.g., VCC) through a resistor (Rocp). The device will automatically detect overcurrent and short-circuit conditions and respond accordingly. Refer to the datasheet for specific implementation guidelines.
The recommended input capacitor value and type depend on the input voltage and frequency. A general guideline is to use a low-ESR ceramic capacitor with a value between 4.7 μF and 10 μF. For specific recommendations, refer to the datasheet and application notes, which provide guidance on input capacitor selection based on the input voltage and frequency.
