ISL6333BCRZ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.
