ISL81601FRZ-T - Renesas Electronics

Description: The ISL81601 is a true bidirectional 4-switch synchronous buck-boost controller with peak and average current sensing and monitoring at both ends. Its wide input and output voltage ranges make it suitable for industrial, telecommunication, and after-market automotive applications.The ISL81601 uses the proprietary buck-boost control algorithm with valley current modulation for Boost mode and peak current modulation for Buck mode control. The ISL81601 has four independent control loops for input and output vo

ISL81601FRZ-T Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power and ground connections.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output capacitor's ESR is less than 1 ohm. Also, avoid using ceramic capacitors with high ESL values.
  • The ISL81601FRZ-T can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and reliability.
  • The output voltage can be calculated using the formula: Vout = (R1/R2) * (Vref), where R1 and R2 are the resistors in the feedback network, and Vref is the internal reference voltage (1.2V).
  • The ISL81601FRZ-T can deliver up to 1A of output current, but it's recommended to keep the output current below 800mA for optimal performance and reliability.
