Multi-Purpose Precision Multi-Phase PWM
Controller With Optional Active Voltage
Positioning
The ISL6558 is a multi-phase PWM controller, which in
combination with the HIP6601B, HIP6602B, HIP6603B, or
ISL6605 companion gate drivers form a complete solution
for high-current, high slew-rate applications. The ISL6558
regulates output voltage, balances load currents and
provides protective functions for two to four synchronous
rectified buck converter channels.
A novel approach to current sensing is used to reduce
overall solution cost and improve efficiency. The voltage
developed across the lower MOSFET during conduction is
sampled and fed back to the controller. This lossless
current-sensing approach enables the controller to maintain
phase-current balance between the power channels, provide
overcurrent protection, and permit droop compensation.
Optional output voltage “droop” or active voltage positioning
is supported via the DROOP pin. Taking advantage of this
feature reduces the size and cost of the output capacitors
required to support a load transient.
In the event of an overvoltage, the controller monitors and
responds to reduce the risk of damage to load devices.
Undervoltage conditions are indicated through a PGOOD
transition. Overcurrent conditions cause the converter to
shutdown limiting the exposure of load devices. These
integrated monitoring and protection features provide a safe
environment for microprocessors and other advanced low
voltage circuits.
