ZL8800ALBFT

Overview

The ZL8800ALBFT is a dual-output or dual-phase digital DC/DC controller from the Digital-DC series. It operates with an input voltage range of 4.5V to 14V and supports output voltages from 0.54V to 5.5V. The device features a switching frequency range of 200kHz to 1.33MHz and utilizes ChargeMode control for transient response. It is housed in a 44-QFN (7x7mm) package and supports PMBus communication. The component is rated for operation between -40°C and +85°C.

Feature Summary

• ChargeMode control enables single-cycle transient response without external compensation
• Digital-DC serial bus allows inter-IC phase current balancing
• Dual configuration supports independent outputs or high-current dual-phase operation

Applications

• High-density server power supplies
• Telecommunications infrastructure equipment
• Industrial automation systems

Procurement Notes

Verify component authenticity through authorized channels as this part is End-of-Life. Confirm RoHS3 compliance and MSL level 2 handling requirements during storage and assembly. Check for specific firmware revisions associated with the suffix if applicable.

Selection Notes

Select this controller for designs requiring precise digital regulation and fast transient recovery. Ensure the application benefits from reduced output capacitance due to ChargeMode technology. Verify that the system architecture supports PMBus integration for monitoring and control.
