ZL8800
Dual Channel/Dual Phase PMBus ChargeMode Control DC/DC Digital Controller
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.
The proprietary single wire Digital-DC™ (DDC) 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
undervoltage protected. One internal temperature sensor and
two external temperature sensors are available for
temperature monitoring, one of which is used for
under-temperature 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
operate 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, and output current as well as the device’s internal
temperature, two external temperatures, and an auxiliary
voltage input.
