ISL6754AAZA-T - 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-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the application note AN1443, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • The input capacitor selection depends on the input voltage, ripple current, and ESR requirements. Renesas recommends using a low-ESR ceramic capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the maximum input voltage. Refer to the application note AN1443 for more details.
  • The maximum allowed output capacitance is not explicitly stated in the datasheet, but Renesas recommends limiting the output capacitance to 100uF or less to ensure stability and prevent oscillations. Larger output capacitances may require additional compensation or stabilization techniques.
  • The ISL6754AAZA-T has a built-in overcurrent protection feature that can be enabled by connecting the OC pin to a resistor and capacitor network. The application note AN1443 provides a detailed example of how to implement overcurrent protection using this method.
  • The recommended operating temperature range for the ISL6754AAZA-T is -40°C to +125°C, but the device can operate up to +150°C with derating. Refer to the datasheet for detailed thermal derating information.
