ISL95338HRTZ-T - Renesas Electronics

Description: The ISL95338 is a bidirectional, buck-boost voltage regulator that provides buck-boost voltage regulation and protection features. The Renesas advanced R3™ Technology provides high light-load efficiency, fast transient response, and seamless DCM/CCM transitions. The ISL95338 takes input power from a wide range of DC power sources (such as conventional AC/DC ADPs, USB PD ports, and travel ADPs) and safely converts it to a regulated voltage up to 20V. The ISL95338 can also convert a wide range DC power source

ISL95338HRTZ-T Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for optimal performance. Renesas recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. The input and output capacitors should be placed close to the IC, and the feedback resistors should be placed close to the output pins. A detailed layout guide can be found in the application note AN1995.
  • To ensure stability and prevent oscillations, it's essential to follow the recommended component values and PCB layout. Additionally, the output capacitors should be chosen to ensure a minimum ESR (Equivalent Series Resistance) of 10mΩ or less. The feedback resistors should be chosen to ensure a minimum bandwidth of 100kHz or higher.
  • Renesas recommends using a 10uF to 22uF X5R or X7R type ceramic capacitor for a low ESR and high ripple current rating. The input capacitor value should be chosen based on the input voltage and current requirements.
  • The output voltage accuracy can be calculated using the formula: VOUT = (VREF x (1 + (R2/R1))) / (1 + (R2/R1)). The output voltage accuracy is also dependent on the tolerance of the resistors and the reference voltage.
  • The ISL95338HRTZ-T can deliver up to 3A of output current. However, the maximum output current capability is dependent on the input voltage, output voltage, and the thermal conditions.
