ISL9305IRTHBCNLZ-T - Renesas Electronics

Description: The ISL9305H is an integrated mini Power Management IC (mini-PMIC) for powering low-voltage microprocessors, or applications using a single Li-Ion or Li-Polymer cell battery to power multiple voltage rails. The ISL9305H integrates two high-efficiency 3MHz synchronous step-down converters (DCD1 and DCD2) and two low-input, low-dropout linear regulators (LDO1 and LDO2). The 3MHz PWM switching frequency allows the use of very small external inductors and capacitors. Both step-down converters can enter skip mod

ISL9305IRTHBCNLZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note AN1995, which includes guidelines for component placement, thermal management, and routing to minimize noise and ensure optimal performance.
  • The ISL9305IRTHBCNLZ-T has a thermal pad that must be connected to a thermal plane on the PCB to dissipate heat. A thermal interface material (TIM) can be used to improve heat transfer. Additionally, the device has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C.
  • Renesas recommends using a 10uF to 22uF ceramic capacitor with an X5R or X7R dielectric as the input capacitor. The capacitor should be placed as close to the VIN pin as possible to minimize noise and ensure stable operation.
  • The ISL9305IRTHBCNLZ-T has a resistive divider network that sets the output voltage. The output voltage can be adjusted by selecting the appropriate values for the feedback resistors RFB1 and RFB2. Renesas provides a calculation tool and guidelines in their datasheet to help with the selection of these resistors.
  • The ISL9305IRTHBCNLZ-T has a soft-start feature that ramps up the output voltage during startup to prevent inrush currents. During shutdown, the device has a controlled shutdown feature that slowly discharges the output capacitor to prevent voltage spikes.
