Product Summary
The IR3088MTR Phase IC combined with an IR XPhase Control IC provides a full featured and flexible way to implement power solutions for the latest high performance CPUs and ASICs. The IR3088MTR 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 IR3088MTR architecture results in a power supply that is smaller, less expensive, and easier to design while providing higher efficiency than conventional approaches.
Parametrics
IR3088MTR absolute maximum ratings: (1)VMAX: 27V; (2)ISOURCE: 50mA; (3)Operating Junction Temperature: 150°C; (4)Storage Temperature Range: -65 to 150°C; (5)GATEH Rise Time VCCH = 12V, Measure 2V to 9V transition time: 22 to 50 ns; (6)Disable Pull-Down Current Force GATH or GATEL = 2V with BIASIN = 0V: 15 to 40 μA.
Features
IR3088MTR features: (1)2.5A Average Gate Drive Current; (2)Loss-Less Inductor Current Sense; (3)Internal Inductor DCR Temperature Compensation; (4)Programmable Phase Delay; (5)Programmable Feed-Forward Voltage Mode PWM Ramp; (6)Sub 100ns Minimum Pulse Width supports 1MHz per-phase operation; (7)Current Sense Amplifier drives a single wire Average Current Share Bus; (8)Current Share Amplifier reduces PWM Ramp slope to ensure sharing between phases; (9)Phase Fault Detection; (10)Programmable Phase Over-Temperature Detection; (11)Small thermally enhanced 20L MLPQ package.
