LM26420Q1XMH/NOPB Frequently Asked Questions (FAQ)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using bypass capacitors to reduce noise and EMI.

  • The selection of input and output capacitors depends on the specific application requirements, such as ripple current, voltage rating, and ESR. TI recommends using low-ESR capacitors with a voltage rating of at least 1.5 times the input voltage. The datasheet provides guidance on capacitor selection, but it's also recommended to consult with capacitor manufacturers for specific recommendations.

  • The LM26420Q1XMH/NOPB is rated for operation up to 125°C, but the maximum ambient temperature for reliable operation depends on the specific application and thermal design. It's recommended to follow the thermal design guidelines in the datasheet and to ensure that the device is properly heat-sinked to maintain a safe operating temperature.

  • To ensure EMC, it's recommended to follow general EMC design guidelines, such as using shielding, filtering, and grounding techniques. The LM26420Q1XMH/NOPB has built-in EMI filtering, but additional filtering may be required depending on the specific application. TI provides guidance on EMC design in the datasheet and application notes.

  • The recommended input voltage range for the LM26420Q1XMH/NOPB is 3.5V to 36V, but the optimal performance range depends on the specific application requirements. It's recommended to consult the datasheet and application notes for guidance on input voltage selection.
