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 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, and output current as well as the device's internal temperature, two external temperatures, and an auxiliary voltage input.

Identifying the differences between the ZL8800 and ZL8801 dual phase PMBus™ ChargeMode™ control dc/dc digital controllers.
The ZL8801 is part of our fourth generation family of digital power controllers. Also in that family is the ZL8800. Selecting between the two is relatively simple, as the chart shows.
The ZL8800 and ZL8801 both offer ChargeMode control. The ZL8800, however, offers dual output or dual phase operation. The ZL8801 offers only dual phase, but it adds DDC current share. With DDC current share, you can share multiple ZL8801 controllers, for up to an eight-phase design.
The recommended current range for the ZL8800 is between 5A and 60A. The ZL8801 has a recommended current range of 40A all the way up to 300A plus. The actual current is dependent on the power stage you use, however, these are just recommendations.
Both parts are offered in a 7mm x 7mm QFN package. Both the ZL8800 and ZL8801 are compensation free, based on our ChargeMode control architecture.
Unlike an analog control loop, a fully digital control loop digitizes the feedback voltage and handles all control and compensation in a digital delay.
