ISL6333ACRZ规格书详情

The ISL6333 three-phase PWM family of control ICs provide a

precision voltage regulation system for advanced

microprocessors. The integration of power MOSFET drivers

into the controller IC marks a departure from the separate PWM

controller and driver configuration of previous multi-phase

product families. By reducing the number of external parts, this

integration is optimized for a cost and space saving power

management solution.

The ISL6333 controllers are designed to be compatible with

Intel VR11.1 Applications. Features that make these controllers

compatible include an IMON pin for output current monitoring,

and a Power State Indicator (PSI#) pin for phase dropping and

higher efficiency during light load states. An 8-bit VID input is

used to select the desired output voltage from the VR11 DAC

table. A circuit is provided for remote voltage sensing,

compensating for any potential difference between remote and

local grounds. The output voltage can also be positively or

negatively offset through the use of a single external resistor.

The ISL6333 controllers also include advanced control loop

features for optimal transient response to load application and

removal. One of these features is highly accurate, fully

differential, continuous DCR current sensing for load line

programming and channel current balance. Active Pulse

Positioning (APP) Modulation and Adaptive Phase Alignment

(APA) are two other unique features, allowing for quicker initial

response to high di/dt load transients. With this quicker initial

response to load transients, the number of output bulk

capacitors can be reduced, helping to reduce cost.

Integrated into the ISL6333 controllers are user-programmable

current sense resistors, which require only a single external

resistor to set their values. No external current sense resistors

are required. Another unique feature of the ISL6333 controllers

is the addition of a dynamic VID compensation pin that allows

optimizing compensation to be added for well-controlled

dynamic VID response.

Protection features of these controller ICs include a set of

sophisticated overvoltage, undervoltage, and overcurrent

protection. Furthermore, the ISL6333 controllers include

protection against an open circuit on the remote sensing inputs.

Combined, these features provide advanced protection for the

microprocessor and power system.
