ISL6754AAZA - Renesas Electronics

Description: The ISL6754 is a high performance extension of the Renesas family of Zero-Voltage Switching (ZVS) full-bridge PWM controllers. Like the ISL6752, it achieves ZVS operation by driving the upper bridge FETs at a fixed 50% duty cycle while the lower bridge FETs are trailing-edge modulated with adjustable resonant switching delays. Adding to the ISL6752’s feature set are average current monitoring and soft-start. The average current signal may be used for average current limiting, current sharing circuits and av

ISL6754AAZA Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the switching components close to the IC, and use a thermal relief pattern under the IC to improve heat dissipation.
  • Use a soft-start circuit to limit the inrush current during start-up, and ensure the input voltage rises slowly (e.g., 10ms to 100ms) to prevent excessive current draw. For shutdown, use a soft-shutdown circuit to gradually reduce the output voltage.
  • Use a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF, depending on the input voltage and output current requirements.
  • Use the datasheet's recommended compensation network values as a starting point, and then adjust the values based on the specific application's requirements and stability analysis using tools like Bode plots or simulation software.
  • The maximum allowed output capacitance is 100uF. Exceeding this value may cause instability or oscillations in the output voltage.
