ISL8107IRZ-T - Renesas Electronics

Description: The ISL8107 is a single phase, non-synchronous buck controller with an integrated high-side MOSFET driver. The controller operates from 9V to 75V input voltage range. The internal 1.192V reference voltage has a tolerance of ±1% over the industrial temperature range. The ISL8107 employs voltage-mode control with feedforward compensation to provide optimal transient response and a constant loop gain over a wide input voltage range. The switching frequency can be programmed from 100kHz to 600kHz by external re

ISL8107IRZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the ISL8107IRZ-T evaluation board user manual, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • The ISL8107IRZ-T has an internal undervoltage lockout (UVLO) circuit that ensures the device is properly biased during startup. To ensure proper biasing, make sure the input voltage rises monotonically and does not drop below the UVLO threshold (typically 2.5V) during startup.
  • The ISL8107IRZ-T can drive capacitive loads up to 10nF, but it's recommended to limit the load capacitance to 4.7nF or less to ensure stable operation and minimize ringing on the output.
  • The output voltage ripple and noise can be calculated using the equations provided in the datasheet, taking into account the input voltage, output voltage, switching frequency, and output capacitance. Additionally, Renesas provides a noise calculation tool on their website to simplify the process.
  • Renesas recommends using a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF as the input capacitor. This helps to filter out input voltage noise and ensure stable operation.
