PIN I/O DESCRIPTION
NAME RGW RGT
50mV, 100mV, 200mV, 400mV, 800mV, 1.6V 5, 6, 7,
9, 10, 11		 4, 5, 6,
8, 9, 10		 I Output voltage setting pins. These pins must be connected to ground or left floating. Connecting these pins to ground increases the output voltage by the value of the pin name; multiple pins can be simultaneously connected to GND to select the desired output voltage. Leave these pins floating (open) when not in use. See the User-Configurable Output Voltage section for more details.
EN 14 12 I Enable pin. Driving this pin to logic high enables the device; driving the pin to logic low disables the device. See the Enable section for more details.
FB 3 2 I Output voltage feedback pin. Connected to the error amplifier. See the User-Configurable Output Voltage and Traditional Adjustable Configuration sections for more details. Connect a 220-pF ceramic capacitor from the FB pin to OUT.
GND 8, 18 7 — Ground pin.
IN 15, 16, 17 13, 14 I Unregulated supply voltage pin. Connect an input capacitor to this pin. See the Input Capacitor Requirements section for more details.
NC 12 — — Not internally connected. The NC pin is not connected to any electrical node. This pin and the thermal pad must be connected to a large-area ground plane. See the Power Dissipation section for more details.
OUT 1, 19, 20 15, 16 O Regulated output pin. A 4.7-μF or larger capacitance is required for stability. See the Output Capacitor Requirements section for more details.
PG 4 3 O Active-high power-good pin. An open-drain output that indicates when the output voltage reaches 90% of the target. See the Power-Good section for more details.
SNS 2 1 I Output voltage sense input pin. See the User-Configurable Output Voltage and Traditional Adjustable Configuration sections for more details.
SS 13 11 — Soft-start pin. Leaving this pin open provides a soft start of the default setting.
Connecting an external capacitor between this pin and ground enables the soft-start function by forming an RC-delay circuit in combination with the integrated resistance on the silicon. See the Soft-Start section for more details.
Thermal Pad — The thermal pad must be connected to a large-area ground plane. If available, connect an electrically-floating, dedicated thermal plane to the thermal pad as well.
