NAME
OUT
FUNCTION
Output Sense and Negative Current-Sense Input. When using the internal preset 5V feedback divider
(FB = BIAS), the controller uses OUT to sense the output voltage. Connect OUT to the negative
terminal of the current-sense element.
Open-Drain Power-Good Output. A logic-high voltage on PGOOD indicates that the output voltage is in
10
PGOOD
regulation. PGOOD is pulled low when the output voltage is out of regulation. Connect a 10k
pullup
resistor from PGOOD to the digital interface voltage.

EP
Power Ground. Connect the input and output filter capacitors’ negative terminals to PGND. Connect
PGND externally to SGND at a single point, typically at the output capacitor return terminal.
Low-Side Gate-Driver Output. DL swings from V BIAS to PGND. If a resistor is needed between DL and the
gate of the MOSFET, contact the factory for optimum value.
Internal 5V Linear Regulator Output. BIAS provides power for bias and gate drive. Connect a 1 μF to
10 μF ceramic capacitor from BIAS to PGND. Connect BIAS and SUP to a 5V rail, if available.
External Inductor Connection. Connect LX to the switched side of the inductor. LX serves as the lower
supply rail for the DH high-side gate driver.
High-Side Gate-Driver Output. DH swings from LX to BST. If a resistor is needed between DH and the gate
of the MOSFET, contact the factory for optimum value.
Boost Flying Capacitor Connection. Connect a ceramic capacitor between BST and LX. See the Boost-
Flying Capacitor Selection section for details.
Exposed Pad. Internally connected to ground. Connect EP to a large contiguous copper plane at SGND
potential to improve thermal dissipation. Do not use as the main ground connection.
