PIN FUNCTIONS (continued)
PIN
DESCRIPTION
NAME NO.
Enable pin with internal pull-up current source. Floating this pin will enable the IC. Pull below 1.2 V to enter low
EN 15 current standby mode. Pull below 0.4 V to enter shutdown mode. The EN pin can be used to implement adjustable
undervoltage lockout (UVLO) using two resistors.
AGND 16 Analog signal ground of the IC. AGND should be connected to PGND at a single point on printed circuit board.
The PowerPAD should be connected to AGND. If possible, use thermal vias to connect to an internal ground plane
PowerPAD 17
for improved power dissipation.
