Description
High Input Voltage. Connect VIN to the drain of the upper-side MOSFET.
Output of the Internal Error Amplifier/IC Enable. When this pin functions as EN, applying 0 V to this pin disables the IC.
Noninverting Input of the Internal Error Amplifier. This is the node where the feedback resistor is connected.
Analog Ground Reference Pin of the IC. All sensitive analog components should be connected to this ground
plane (see the Layout Considerations Section).
Bias Voltage Supply for the ADP1872/ADP1873 Controller (Includes the Output Gate Drivers). A bypass capacitor
of 1 μF directly from this pin to PGND and a 0.1 μF across VDD and GND are recommended.
Drive Output for the External Lower Side, N-Channel MOSFET. This pin also serves as the current-sense gain
setting pin (see Figure 68).
Power GND. Ground for the lower side gate driver and lower side, N-channel MOSFET.
Drive Output for the External Upper Side, N-Channel MOSFET.
Switch Node Connection.
Bootstrap for the Upper Side MOSFET Gate Drive Circuitry. An internal boot rectifier (diode) is connected
between VDD and BST. A capacitor from BST to SW is required. An external Schottky diode can also be
connected between VDD and BST for increased gate drive capability.
