S-5852ABCBC-A8T1U4 datasheet by ABLIC Inc.

S-5852ABCBC-A8T1U4 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  ABLIC recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
• How do I ensure the device is properly powered on and off?
  The device requires a soft-start power-on sequence to prevent inrush currents. ABLIC recommends a power-on sequence of EN > VIN > VOUT, and a power-off sequence of VOUT > VIN > EN.
• What is the maximum capacitance value for the output capacitor?
  The maximum capacitance value for the output capacitor is 47uF. Exceeding this value may cause instability or oscillation in the device.
• Can I use this device in a high-temperature environment?
  The S-5852ABCBC-A8T1U4 is rated for operation up to 105°C. However, ABLIC recommends derating the output current and voltage to ensure reliable operation in high-temperature environments.
• How do I troubleshoot oscillation or instability issues?
  Check the PCB layout for proper thermal design, ensure the input and output capacitors meet the recommended specifications, and verify the power-on sequence is correct. If issues persist, consult ABLIC's application notes or contact their support team.
