UC2526ADWTR datasheet by Texas Instruments

UC2526ADWTR Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the UC2526ADWTR?
  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.
• How do I choose the right input and output capacitors for the UC2526ADWTR?
  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.
• What is the maximum ambient temperature range for the UC2526ADWTR?
  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.
• How do I implement overcurrent protection with the UC2526ADWTR?
  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.
• What is the recommended input voltage range for the UC2526ADWTR?
  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.
