PRODUCTION DATA
Pin | I/O | Description | |
---|---|---|---|
Name | Number | ||
VIN | 1, 2 | I | Power supply input pin. Ensure the input capacitor is connected as close as possible between the VIN and GND pins. |
EN | 3 | I | Enable input pin. Connect to logic low to disable the device. Pull high to enable the device. Do not leave this pin unconnected. |
MODE/ S-CONF | 4 | I | Device mode selection (auto PFM/PWM or forced PWM operation) and SmartConfig™ application. Connect high, low, or to a resistor to configure the device according to Table 7-2. Do not leave this pin unconnected. |
SS/TR | 5 | I | Soft start/tracking pin. An external capacitor connected from this pin to GND defines the rise time for the internal reference voltage. The pin can also be used as an input for tracking and sequencing. The pin can be left floating for the fastest ramp-up time. |
PG | 6 | O | Open-drain power-good output. High = VOUT is ready. Low = VOUT is below nominal regulation. This pin requires a pullup resistor. |
FB/VSET | 7 | I | Depends on device configuration (see Section 7.3.1)
|
SW/NC | 8 | NC | Switch pin of the converter. Do not connect, leave floating. |
VOUT | 9, 10 | O | Output voltage pin. Connect directly to the positive pin of the output capacitor. |
GND | 11 | — | Ground pin. It must be connected directly to the common ground plane. It must be soldered to achieve appropriate power dissipation and mechanical reliability. |
