Pin connections and functions
9/50
11
OCL
A resistor connected from this pin to ground sets the valley- current-limit. The
valley current is sensed through the low-side MOSFET(s). The internal current
generator sources a current of 100
A (IOCL) from this pin to ground through the
external resistor (ROCL). The over-current threshold is given by the following
equation:
Connecting a capacitor from this pin to GND helps in reducing the noise
injected from VCC to the device, but can be a low impedance path for the high-
frequency noise related to the GND. Connect a capacitor only to a “clean”
GND.
12
OCH
A resistor connected from this pin and the high-side MOSFET(s) drain sets the
peak-current-limit. The peak current is sensed through the high-side
MOSFET(s). The internal 100
A current generator (IOCH) sinks a current from
the drain through the external resistor (ROCH). The over-current threshold is
given by the following equation:
13
PHASE
This pin is connected to the source of the high-side MOSFET(s) and provides
the return path for the high-side driver. This pin monitors the drop across both
the upper and lower MOSFET(s) for the current limit together with OCH and
OCL.
14
HGATE
This pin is connected to the high-side MOSFET(s) gate.
15
BOOT
Through this pin is supplied the high-side driver. Connect a capacitor from this
pin to the PHASE pin and a diode from VCCDR to this pin (cathode versus
BOOT).
16
PGND
This pin has to be connected closely to the low-side MOSFET(s) source in
order to reduce the noise injection into the device.
17
LGATE
This pin is connected to the low-side MOSFET(s) gate.
18
VCCDR
5V internally regulated voltage. It is used to supply the internal drivers and as a
voltage reference. Filter it to ground with at least 1F ceramic cap.
19
VCC
Supply voltage pin. The operative supply voltage range is from 4.5V to 14V.
20
PGOOD
This pin is an open collector output and it is pulled low if the output voltage is
not within the specified thresholds (90%-110%). If not used it may be left
floating. Pull-up this pin to VCCDR with a 10K resistor to obtain a logical signal.
