This table gives cross-reference parts and alternative options found for UC2886D. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of UC2886D, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
TI recommends a compact layout with the UC2886D placed close to the input capacitors and the output inductor. The input and output traces should be kept short and away from sensitive analog signals. A solid ground plane and a shielded enclosure can also help reduce EMI and noise.
Choose input capacitors with low ESR and high ripple current rating to minimize voltage drops and ensure stable operation. Output capacitors should have low ESR and be rated for the output voltage and current. TI recommends using ceramic or film capacitors with X7R or X5R dielectrics.
The UC2886D is rated for operation from -40°C to 85°C ambient temperature. However, the device's internal temperature should not exceed 125°C to ensure reliable operation and prevent thermal shutdown.
The output voltage of the UC2886D can be adjusted by changing the resistive divider ratio of the feedback resistors (R1 and R2) connected to the FB pin. The output voltage can be calculated using the formula: Vout = 2.5V x (1 + R2/R1).
The bootstrap capacitor (CBOOT) is used to generate the gate drive voltage for the high-side MOSFET. It is charged through the internal bootstrap diode and discharged through the high-side MOSFET during the switching cycle. A 1nF to 10nF ceramic capacitor is recommended for CBOOT.
