NAME
FUNCTION
1V Reference Output. Bypass BUF to GND with a 1μF or larger ceramic capacitor.
4
BUF
Connect a resistor from COMP to BUF to set the load-line. See the Loop-Compensation
Design section for more details.
7, 10, 37, 47
N.C.
No Internal Connection
Phase 4 Current-Sense Positive Input. Connect CS4+ to the positive side of the output
15
CS4+
current-sense resistor, or the positive side of the filtering capacitor if inductor DCR
current sensing is used.
16
CS34-
Phases 3 and 4 Current-Sense Common Negative Input. Connect to the load side of
the output current-sensing elements.
PWM Signal Output for Phase 4. PWM4 is low during shutdown, UVLO, and OVP faults.
22
PWM4
Connect PWM4 to V CC to enable 3-phase operation. Connect PWM3 and PWM4 to V CC
to enable 2-phase operation.
Phase 1 Low-Side MOSFET Gate-Drive Supply. Connect VL1 to a 4.5V to 6.5V supply.
30
VL1
VL1 must be connected to VL2 externally. Bypass the VL1/VL2 connection with a 2.2μF
or larger ceramic capacitor to the power ground plane.
Phase 2 Low-Side MOSFET Gate-Drive Supply. Connect VL2 to a 4.5V to 6.5V supply.
31
VL2
VL2 must be connected to VL1 externally. Bypass the VL1/VL2 connection with a 2.2μF
or larger ceramic capacitor to the power ground plane.
EP
Exposed Paddle. Connect to the analog GND plane for enhanced thermal power
dissipation.
