IR3088A
XPHASE
TM
PHASE IC WITH FAULT AND OVERTEMP DETECT
DESCRIPTION
The IR3088A Phase IC combined with an IR
XPhase
TM
Control IC provides a full featured and flexible way to
implement power solutions for the latest high performance CPUs and ASICs. The “Control” IC provides
overall system control and interfaces with any number of “Phase” ICs which each drive and monitor a single
phase of a multiphase converter. The
XPhase
architecture results in a power supply that is smaller, less
expensive, and easier to design while providing higher efficiency than conventional approaches.
The IR3088A is intended for the following application conditions;
Excessive impedance between converter and load
Output voltage exceeding the control IC reference/VID voltage is desired
FEATURES
2.5A Average Gate Drive Current
Loss-Less Inductor Current Sense
Internal Inductor DCR Temperature Compensation
Programmable Phase Delay
Programmable Feed-Forward Voltage Mode PWM Ramp
Sub 100ns Minimum Pulse Width supports 1MHz per-phase operation
Current Sense Amplifier drives a single wire Average Current Share Bus
Current Share Amplifier reduces PWM Ramp slope to ensure sharing between phases
Body Braking
TM
disables Synchronous MOSFET for improved transient response and prevents negative
output voltage at converter turn-off
Phase Fault Detection
Programmable Phase Over-Temperature Detection
Control FET driver’s 25V input voltage capability simplifies boot-strap supply design
Small thermally enhanced 20L MLPQ package
