DESCRIPTION
  
The IR3588 is a flexible single loop digital multi-phase
buck controller that can be configured as a 1, 2 or 4
phase system when combined with the IR Dual 6x8mm
IR3548 or 5x6mm IR3552.
Power consumption is minimized while maintaining full
digital capability and flexibility. Digital non-linear transient
control allows lower frequency operation to achieve the
highest efficiency possible while providing minimal all
ceramic output capacitor solutions. The IR3588 includes
IR’s Efficiency Shaping Technology to automatically
deliver exceptional efficiency at minimum cost across the
entire load range and can be configured to enter 1-phase
operation and active diode emulation mode automatically
or by command. The IR3588 may also shut down
connected drivers/PowIRstage to minimize the quiescent
current consumption in the system.
IR’s unique Adaptive Transient Algorithm (ATA), based
on proprietary non-linear digital PWM algorithms,
minimizes output bulk capacitors, and improves transient
response and form factor.
Device configuration and fault parameters are easily
defined using the IR Digital Power Design Center (DPDC)
GUI and stored in on-chip MTP. MTP storage saves pins
and enables a small package size. Fault protection
includes output OV, UV and OC protection, thermistor or
Diode based OT protection sensing with a VRHOT signal
output and a Over Current warning flag.
