ZL8800ALAFT規(guī)格書(shū)詳情

The ZL8800 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.

The ZL8800 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 ZL8800 will

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.

Intersil’s proprietary single wire DDC (Digital-DC?) serial bus

enables the ZL8800 to communicate between other Intersil

ICs. By using the DDC, the ZL8800 achieves complex functions

such as inter-IC phase current balancing, sequencing and fault

spreading, eliminating complicated power supply managers

with numerous external discrete components.

The ZL8800 features cycle-by-cycle output overcurrent

protection. The input voltage, output voltages and

DrMOS/MOSFET driver supply voltages are overvoltage and

overvoltage protected. Two external and one internal

temperature sensor are available for temperature monitoring,

one of which is used for under and over-temperature

protection. A snapshot parametric capture feature allows

users to take a snapshot of operating and fault data during

normal or fault conditions.

Integrated Low Dropout (LDO) regulators allow the ZL8800 to

be operated from a single input supply eliminating the need

for additional linear regulators. The LDO output can be used to

power external drivers or DrMOS devices.

With full PMBus? compliance the ZL8800 is capable of

measuring and reporting input voltage, input current, output

voltage, output current as well as the device’s internal

temperature, 2 external temperatures and an auxiliary voltage

input.
