FEATURES DESCRIPTIONS (CON.)
PIN FUNCTIONS
COMP/EN, Pin 1
The COMP/EN pin is a multiplexed pin. When the
Comp/EN pin is pulled below the falling threshold
voltage (0.4V normal), the MCM12S10Q A will be off.
The external pull down device (open collector or open
drain) will initially need to overcome maximum of 5mA of
Pin output current. Once the MCM12S10Q A is
disabled, only a 20uA current source will continue to
draw current.
PGND, Pin 2, 6, 11
Power Ground, these 3 pins are the return path for input
and output current.
VBIAS Pin 3
The VBIAS pin provides the bias voltage for the
MCM12S10Q A. It is normally connected to the VIN pin
(Pin 9).
NC, Pin 4, 5, 8, 14
These four pins have no function. Please do not connect
any trace to these 4 pins.
OCP, Pin 7
The OCP pin is used to set the over current protection
(OCP) and short-circuit protection (SCP) set point.
MCM12S10Q A initial OCP set point is 20A (typ) when
this pin is left open. Connect a resistor between the
OCP pin and the PGND pin will change the OCP set
point.
DS_MCM12S10Q_07022008
VIN, Pin 9
This pin should be tied directly to the input rail. It
provides power to the MCM12S10Q A.
PHASE, Pin 10
This pin connects to the source of the high side
MOSFET and the drain of the low side MOSFET inside
the module. This pin is used as heatsink.
Vout, Pin 12
Power Output Pin, it should be connected to the positive
rail of the load. Apply output load between this pin and
PGND pin. Suggest placing high frequency output
decoupling capacitance as near as possible directly
between this pin and PGND pin. Please refer this
datasheet output capacitance item
Vo, Pin 13
Power Output Pin, same as Vout pin above.
FB, Pin 15
This pin is used to adjust the output voltage. Please add
a resistor between the FB pin and PGND pin to set the
output voltage.
