ZL8800ALBFT7A

Overview

The ZL8800ALBFT7A 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 switching frequency ranges from 200kHz to 1.33MHz. It features a PMBus interface, clock synchronization, and control characteristics including current limiting, enable, power good, and tracking. The device is housed in a 44-QFN (7x7) package and operates within a temperature range of -40°C to 85°C.

Feature Summary

Utilizes ChargeMode control for single-cycle transient response without compensation
Supports independent dual outputs or dual-phase configuration for high current
Enables complex inter-IC functions via proprietary Digital-DC serial bus

Applications

High current applications requiring dual phase operation
Designs minimizing output capacitance for cost and board space savings
Systems requiring inter-IC phase current balancing

Procurement Notes

Verify component status as this product is listed as obsolete. Confirm availability through authorized distributors or secondary markets. Check for RoHS compliance and moisture sensitivity level requirements during handling. Ensure design-in compatibility with existing system constraints given the end-of-life status.

Selection Notes

Select this controller for applications needing fast transient response and minimal output capacitance. Consider the dual-output flexibility for independent rails or combined high-current phases. Verify interface compatibility with PMBus or Digital-DC systems. Evaluate thermal performance within the specified operating temperature range.
