ZL8801 - Control DC/DC Digital Controller

Datasheet Summary

Description

br>

Features

cycle-by-cycle overcurrent protection and protection for overvoltage, undervoltage, over-temperature and MOSFET driver under and overvoltage protection. A snapshot parametric capture feature allows users to take a snapshot of operating and fault data during normal or fault conditions. Integrated Low Drop-Out (LDO) regulators allow the ZL8801 to be operated from a single input supply eliminating the need for additional linear regulators. A dedicated 5V VDRV LDO output can be used to power externa.

DATASHEET ZL8801 Dual Phase PMBus™ ChargeMode™ Control DC/DC Digital Controller FN8614 Rev.3.00 March 27, 2015 The ZL8801 is a dual phase digital DC/DC controller. Up to four ZL8801s (8 phases) can be operated in parallel to provide additional output current. The ZL8801 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 its fully digital ChargeMode™ Control loop the ZL8801 can respond to a transient load step within a single switching cycle. This unique compensation-free modulation technique allows designs to meet transient specifications with minimum output capacitance, thus saving cost and board space.
