UC2526ADWTR Frequently Asked Questions (FAQs)

  • It's essential to follow a good layout and placement strategy to minimize electromagnetic interference (EMI) and ensure proper operation. TI recommends placing the IC close to the input capacitors, using a solid ground plane, and keeping the input and output traces separate.
  • The choice of input and output capacitors depends on the specific application and operating conditions. TI recommends using low-ESR capacitors with a minimum capacitance of 10uF for the input and 22uF for the output. The capacitor selection should also consider the voltage rating, ripple current, and temperature range.
  • The UC2526ADWTR is rated for operation from -40°C to 125°C. However, the maximum ambient temperature range may vary depending on the specific application and thermal design. It's essential to ensure proper thermal management to prevent overheating and ensure reliable operation.
  • The UC2526ADWTR has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) between the output and the GND pin. The IC will shut down when the current exceeds the threshold set by the sense resistor value. TI recommends using a sense resistor value between 0.1Ω and 1Ω.
  • The UC2526ADWTR can operate with an input voltage range of 7V to 18V. However, the recommended input voltage range is 9V to 15V for optimal performance and efficiency.
