L6713A 2/3 phase controller with embedded drivers for Intel VR10, VR11 and AMD 6 bit CPUs

L6713A implements a two/three phase step-down controller with 180º/120º phase-shift between each phase with integrated high current drivers in a compact 10x10 mm body package with exposed pad.The 2 or 3 phase operation can be easily selected through PHASE_SEL pin.

Load transient boost LTB Technology™ (patent pending) reduces system cost by providing the fastest response to load transition therefore requiring less bulk and ceramic output capacitors to satisfy load transient requirements.

LTB Technology™ can be disabled and in this condition the device works as a dual-edge asynchronous PWM.

The device embeds selectable DACs: the output voltage ranges up to 1.60000 V (both Intel VR10.x and VR11 DAC) or up to 1.5500 V (AMD 6BIT DAC) managing D-VID with ± 0.5% output voltage accuracy over line and temperature variations.

The controller assures fast protection against load over current and under / over voltage (in this last case also before UVLO). In case of over-current the device turns off all MOSFET and latches the condition.

System thermal monitor is also provided allowing system protection from over-temperature conditions
