PRODUCTION DATA
Pin | Type(1) | Description | |
---|---|---|---|
Name | Number | ||
PG | 1 | O | Open-drain power-good output. High = VOUT is ready. Low = VOUT is below nominal regulation. This pin requires a pullup resistor. |
SW | 2 | — | Switch pin of the converter and is connected to the internal power switches. Connect the inductor between SW and the output capacitor. |
VOS | 3 | I | Output voltage sense pin. Connect directly to the positive pin of the output capacitor. |
GND | 4 | — | Ground pin. This pin must be connected directly to the common ground plane. |
EN | 5 | I | Enable input pin. Connect to logic low to disable the device. Pull high to enable the device. Do not leave this pin unconnected. |
VIN | 6 | I | Power supply input pin. Ensure the input capacitor is connected as close as possible between the VIN and GND pins. |
MODE/ S-CONF |
7 | I | Device mode selection (auto PFM/PWM or forced PWM operation) and SmartConfig pin. Connect high, low, or to a resistor to configure the device according to Table 8-1. Do not leave this pin unconnected. |
SS/TR | 8 | I | Soft start and 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. |
FB/VSET | 9 | I | Depends on device
configuration (see Section 8.3.1.)
