ZL8800
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 Zilker 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 Drop-Out (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.
