ISL95870BIRZ - Renesas Electronics

Description: The ISL95870, ISL95870A, ISL95870B ICs are Single-Phase Synchronous-Buck PWM regulators featuring Intersil’s proprietary R4 Technology™. The wide 3. 3V to 25V input voltage range is ideal for systems that run on battery or AC-adapter power sources. The ISL95870A and ISL95870B are low-cost solutions for applications requiring dynamically selected slew-rate controlled output voltages. The soft-start and dynamic setpoint slew-rates are capacitor programmed. Voltage identification logic-inputs select four (ISL9

ISL95870BIRZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the switching components close to the IC, and use short, wide traces for the power lines. Avoid routing sensitive analog signals near the switching components.
  • The compensation network can be optimized by using the datasheet's recommended values as a starting point and then adjusting the values based on the specific application's requirements. A network analyzer or a Bode plot can be used to measure the loop gain and adjust the compensation network for optimal stability and transient response.
  • The ISL95870BIRZ can handle input voltages up to 25V, but the maximum recommended input voltage is 20V to ensure reliable operation and to prevent damage to the IC.
  • Ensure good airflow around the IC, use a heat sink if necessary, and keep the IC away from other heat sources. Monitor the IC's temperature using the thermal monitoring pin (TMP) and adjust the system design accordingly to prevent overheating.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. The capacitor should be placed close to the IC's input pins to minimize noise and ensure stable operation.
