ZL8802ALAFT7A - Renesas Electronics

Description: The ZL8802 is a dual output or dual phase digital DC/DC controller. Each output can operate independently or be used together in a dual phase configuration for high current applications supporting 2-, 4-, 6-, and 8-phase operation with up to four ZL8802 controllers. The ZL8802 supports a wide range of output voltages (0. 54V to 5. 5V) operating from input voltages as low as 4. 5V up to 14V. With the fully digital ChargeMode control, the ZL8802 will respond to a transient load step within a single switching

ZL8802ALAFT7A Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to ensure efficient heat dissipation.
  • Ensure that the input voltage rises and falls monotonically, and that the enable pin is properly driven to prevent unwanted start-up or shutdown. A soft-start circuit can also be used to reduce inrush current.
  • The maximum allowed capacitance on the output is 220uF. Exceeding this value may cause instability or oscillations in the output voltage.
  • The output voltage can be adjusted by changing the resistor divider ratio on the feedback pins. A calculation tool or simulation software can be used to determine the optimal resistor values.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for input decoupling. The capacitor should be placed close to the device's input pins.
