Dual Channel/Dual Phase PMBus ChargeMode Control DC/DC Digital Controller

The ZL8800 is a dual output or dual phase digital DC/DC

Features

controller. Each output can operate independently or be used

together in a dual phase configuration for high current

applications.

• Unique compensation-free design, which is always stable

• Output voltage range: 0.54V to 5.5V

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.

• Input voltage range: 4.5V to 5.5V or 6.5V to 14V

• 1% output voltage accuracy over line, load, and temperature

• ChargeMode control achieves fast transient response and

reduced output capacitance and provides output stability

without compensation

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.

• Switching frequency range: 200kHz to 1.33MHz

• Proprietary single wire DDC serial bus enables voltage

sequencing and fault spreading with other Intersil ICs

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.

• External power supply tracking

• Cycle-by-cycle inductor peak current protection

• Digital fault protection for output voltage UV/OV, input

voltage UV/OV, temperature, and MOSFET driver voltage

• 10-bit average output current measurement with adjustable

gain settings for sensing with high current, low DCR

inductors

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.

• 10-bit monitor ADC measures input voltage, input current,

output voltage, internal and external temperature, and driver

voltage

• Configurable to use standalone MOSFET drivers or

integrated Driver-MOSFET (DrMOS) devices

• Nonvolatile memory for storing operating parameters and

fault events

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.

• PMBus compliant

Applications

• Servers and storage equipment

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.

• Telecom and datacom equipment

• Power supplies (memory, DSP, ASIC, FPGA)
