Pin Function
Bootstrap pin. A capacitor is connected between BST to LX to develop the floating voltage for the
high-side gate drive.
Power input supply voltage.
Switching (Phase) node.
Power ground.
Open-drain Power Good indicator. High impedance indicates power is good. An external pull-up
resistor is required.
Feedback input for switching regulator. Connect to an external resistor divider from the output to
program the output voltage.
Tri-state pin. Enable input for switching regulator. Pull EN/PSV high to enable the part with power
save mode enabled. Connect EN/PSV to AGND to disable the switching regulator. Leave EN/PSV
floating to enable the IC in forced continuous conduction mode.
On-time set input. Set the on-time by a series resistor to AGND .
Analog Ground.
Input power for internal control circuit. Needs 1 m F decoupling capacitor from this pin to AGND.
PAD
? 2010 Semtech Corporation
Thermal pad for heatsinking purposes. Connect to ground plane using multiple vias. Not con-
nected internally.
