NAME
DESCRIPTION
GA
Analog Ground. Connect GAs directly to a quiet ground node. Connect GAs and GP12 to-
gether at a single point as close to the IC as possible.
FB1
Feedback Sense for REG1. Connect this pin to the LED string current sense resistor to sense
the LED current.
OVP1
Over-Voltage Protection Input for REG1. Connect this pin directly to the output node to sense
and prevent over-voltage conditions.
SW1 Switching Node Output for REG1. Connect this pin to the switching end of the inductor.
GP12
Power Ground for REG1, REG2. Connect GP12 directly to a power ground plane. Connect
GAs and GP12 together at a single point as close to the IC as possible.
SW2 Switching Node Output for REG2. Connect this pin to the switching end of the inductor.
OVP2
Over-Voltage Protection Input for REG2. Connect this pin directly to the output node to sense
and prevent over-voltage conditions.
FB2
Feedback Sense for REG2. Connect this pin to the center point of a resistive voltage divider
to sense output voltage.
ON2
Enable Control Input for REG2. Drive ON2 to IN or to a logic high for normal operation, drive
to GA or a logic low to disable REG2.
ON1
Enable Control Input for REG1. Drive ON1 to IN or to a logic high for normal operation, drive
to GA or a logic low to disable REG1.
IN Power Input for the IC. Bypass IN to GA with a capacitor placed as close as possible to the IC.
EP Exposed Pad. Must be soldered to ground on the PCB.
