ISL6617A规格书详情
The ISL6617A utilizes Intersil’s proprietary Phase Doubler
scheme to modulate two-phase power trains with single PWM
input. It doubles the number of phases that 3.3V multiphase
controllers can support.
The ISL6617A is designed to minimize the number of analog
signals that interface between the controller and drivers in high
phase count scalable applications. The common COMP signal,
which is usually seen in conventional cascaded configurations, is
not required; this improves noise immunity and simplifies the
layout. Furthermore, the ISL6617A provides low part count and
low cost advantage over the conventional cascaded technique.
By cascading the ISL6617A with another ISL6617 or ISL6611A, it
can quadruple the number of phases that 3.3V multiphase
controllers can support.
The ISL6617A also features tri-state input and outputs that
recognize a high-impedance state, working together with Intersil
multiphase PWM controllers and driver stages to prevent
negative transients on the controlled output voltage when
operation is suspended. This feature eliminates the need for the
Schottky diode that may be utilized in a power system to protect
the load from excessive negative output voltage damage.
Features
• Proprietary phase doubler scheme
• Enhanced light to full load efficiency
• Double or quadruple phase count
• Patented current balancing with DCR current sensing and
adjustable gain
• Current monitoring output (IOUT) to simplify system interface
and layout
• Triple-level enable input for mode selection
• Dual PWM output drives for two synchronous rectified bridges
with single PWM input
• Channel synchronization and two interleaving options
• Support 3.3V PWM input
• Support 5V PWM output
• Tri-state PWM input and outputs for output stage shutdown
• Overvoltage protection
• Dual flat no-lead (DFN) package
- Near chip-scale package footprint; improves PCB utilization, thinner profile
- Pb-free (RoHS compliant)
Applications
• High current low voltage DC/DC converters
• High frequency and high efficiency VRM and VRD
• High phase count and phase shedding applications
• 3.3V PWM input integrated power stage or DrMOS
