Description
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 10x10mm 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 1.60000V (both Intel VR10.x
and VR11 DAC) or up to 1.5500V (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.
