Functional description
7.1 Pin functions
7.1.1
Output stage supply (V
DDO
, V
SSO
)
The power output stage of the PIP250M consists of two N-channel, power MOSFETs
and a Schottky diode configured as a synchronous buck converter. The drain of the
upper MOSFET is connected to the positive conversion supply (V
DDO
), and the
source of the lower MOSFET is connected to power ground (V
SSO
). The Schottky
diode is connected between the source and drain of the lower MOSFET.
7.1.2
Output voltage (VO)
VO is the switched node of the power MOSFET output stage. This node is connected
internally to the source of the upper MOSFET and the drain of the lower MOSFET.
7.1.3
Control circuit supply (V
DDC
, V
SSC
)
V
DDC
is the positive supply to the control circuit. V
SSC
is the control circuit ground. All
control voltages are measured with respect to V
SSC
.
7.1.4
Bootstrap capacitor connection (CB)
The upper MOSFET driver stage is powered from the CB pin.
7.1.5
Voltage feedback pin (FB)
The FB pin is connected to the inverting input of the error amplifier, and to the inputs
of the overvoltage and undervoltage comparators.
7.1.6
Current limit set and enable input (OCSET/ENABLE)
The overcurrent threshold is set by an external resistor between V
DDO
and
OCSET/ENABLE. The PIP250M can be shut down by pulling this pin LOW.
7.1.7
Sense connection for current limit (PHASE)
The PHASE input is normally connected externally to the power output stage
switched node (VO). The voltage on the PHASE input is compared with the voltage
on the OCSET/ENABLE input during the interval when the upper MOSFET is on. The
overcurrent trip operates if the voltage on the PHASE input is lower than the voltage
on the OCSET/ENABLE input.
