ZL8802ALAFTK - 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

ZL8802ALAFTK 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 monotonically and does not droop during start-up. Also, ensure that the enable pin is properly driven and de-bounced to prevent unwanted start-ups.
  • The output voltage accuracy is affected by the tolerance of the internal voltage reference, the resistor divider network, and the output voltage sensing circuitry. Ensure that high-precision resistors are used in the divider network.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke to reduce EMI. Also, ensure that the PCB layout is optimized for minimal loop area and radiation.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10-22uF is recommended. The capacitor should be placed close to the input pins to minimize inductance.
