FUNCTION
External Inductor Connection for OUT2. Connect to the switched side of the inductor. LX2 serves as the
lower supply voltage rail for the DH2 high-side gate driver and is the positive input to the OUT2 current-limit
comparator.
High-Side Gate Driver Output for OUT2. Swings from LX2 to BST2.
Boost Flying Capacitor Connection for OUT2. Connect to an external capacitor and diode according to the
Standard Application Circuit (Figure 1). See MOSFET Gate Drivers (DH_, DL_) section.
Low-Side Gate-Driver Output for OUT2. DL2 swings from PGND to V DD .
Supply Input for the DL Gate Drivers. Connect to the system supply voltage, +4.5V to +5.5V. Bypass to
PGND with a minimum 4.7μF ceramic capacitor.
Analog-Supply Input. Connect to the system supply voltage, +4.5V to +5.5V, with a 20 Ω series resistor.
Bypass to AGND with a 1μF ceramic capacitor.
Power Ground. Connect directly to the low-side MOSFETs’ sources. Serves as the negative input of the cur-
rent-sense amplifiers.
Low-Side Gate Driver Output for OUT1. DL1 swings PGND to V DD .
Boost Flying Capacitor Connection for OUT1. Connect to an external capacitor and diode according to the
Standard Application Circuit (Figure 1). See MOSFET Gate Drivers (DH_, DL_) section.
High-Side Gate Driver Output for OUT1. Swings from LX1 to BST1.
External Inductor Connection for OUT1. Connect to the switched side of the inductor. LX1 serves as the
lower supply voltage rail for the DH1 high-side gate driver.
