Device description
L6706 is single phase PWM controller with embedded high current drivers providing
complete control logic and protections for a high performance step-down DC-DC voltage
regulator optimized for advanced microprocessor power supply.
L6706 is a dual-edge asynchronous PWM controller featuring load transient boost LTB
Technology: the device turns on the phase as soon as a load transient is detected
allowing to minimize system cost by providing the fastest response to load transition. Load
transition is detected (through LTB pin) measuring the derivate dV/dt of the output voltage
and the dV/dt can be easily programmed extending the system design flexibility. Moreover,
load transient boost (LTB) Technology gain can be easily modified in order to keep under
control the output voltage ring back.
LTB Technology can be disabled and in this condition the device works as a dual-edge
asynchronous PWM.
L6706 permits easy system design by allowing current reading across inductor in fully
differential mode. Also a sense resistor in series to the inductor can be considered to
improve reading precision.
The controller allows compatibility with both Intel VR11.0 and VR11.1 processors
specifications, also performing D-VID transitions accordingly.
The device is VR11.1 compatible implementing IMON signal.
Low-side-less startup allows soft-start over pre-biased output avoiding dangerous current
return through the main inductor as well as negative spike at the load side.
L6706 provides a programmable over-voltage protection to protect the load from dangerous
over stress, latching immediately by turning ON the lower driver and driving high the
OSC/FAULT pin. Furthermore, preliminary OVP protection also allows the device to protect
load from dangerous OVP when VCC is not above the UVLO threshold or OUTEN is low.
The overcurrent protection is externally adjustable through a single resistor. The device
keeps constant the peak of the inductor current ripple working in constant current mode until
the latched UVP.
A compact 6 x 6 mm body VFQFPN-40 package with exposed thermal pad allows
dissipating the power to drive the external MOSFET through the system board.
