Pins description
Voltage IDentification pins.
Internally pulled-up to 3V, connect to SGND to program a logic ‘0’ while leave floating (as well
as pull-up with a resistor up to 3.3V) to program a logic ‘1’.
They are used to program the output voltage as specified in
VID_SEL and to set the OVP/UVP protection thresholds accordingly.
See relevant section for details about DAC selection.
VID_SELect pin. Through this pin it is possible to select the DAC table used for the regulation.
Leave floating to use a VRD10.x compliant DAC (See
VRM-Hammer compliant DAC (See
See relevant section for details about DAC selection.
Soft start end signal. It is an open collector output, set free after finishing the soft start.
Pull-up with a resistor to a voltage lower than 5V, if not used may be left floating.
All the internal references are referred to this pin. Connect it to the PCB signal ground.
Channel 3 HS driver return path. It must be connected to the HS3 mosfet source and provides
the return path for the HS driver of channel 3.
Channel 3 HS driver output.
A little series resistor helps in reducing device-dissipated power.
Channel 3 HS driver supply. This pin supplies the relative high side driver.
Connect through a capacitor (100nF Typ.) to the PHASE3 pin and through a diode to VCC
(cathode vs. boot).
Channel 3 LS driver return path.
Connect to Power Ground Plane.
Channel 3 LS driver output.
A little series resistor helps in reducing device-dissipated power.
Not internally connected.
Channel 3 LS driver supply: it can be varied from 5V to 12V buses.
It must be connected together with other VCCDRx pins.
Filter locally with at least 1 F ceramic cap vs. PGND3.
Channel 2 LS driver return path.
Connect to Power Ground Plane.
Channel 2 LS driver output.
