Description
1
VIN
High Input Voltage. Connect VIN to the drain of the upper-side MOSFET.
2
COMP/EN
Output of the Internal Error Amplifier/IC Enable. When this pin functions as EN, applying 0 V to this pin disables the IC.
3
FB
Noninverting Input of the Internal Error Amplifier. This is the node where the feedback resistor is connected.
4
GND
Analog Ground Reference Pin of the IC. All sensitive analog components should be connected to this ground
plane (see the Layout Considerations section).
5
VREG
Internal Regulator Supply Bias Voltage for the ADP1870/ADP1871 Controller (Includes the Output Gate Drivers).
A bypass capacitor of 1 μF directly from this pin to PGND and a 0.1 μF across VREG and GND are recommended.
6
DRVL
Drive Output for the External Lower-Side, N-Channel MOSFET. This pin also serves as the current-sense gain
setting pin (see Figure 69).
7
PGND
Power GND. Ground for the lower-side gate driver and lower-side, N-channel MOSFET.
8
DRVH
Drive Output for the External Upper-Side, N-Channel MOSFET.
9
SW
Switch Node Connection.
10
BST
Bootstrap for the Upper-Side MOSFET Gate Drive Circuitry. An internal boot rectifier (diode) is connected
between VREG and BST. A capacitor from BST to SW is required. An external Schottky diode can also be
connected between VREG and BST for increased gate drive capability.
