5 Pin Configuration and Functions

TPS62860 TPS62861 8-Pin DSBGA YCH Package (Top View) Figure 5-1 8-Pin DSBGA YCH Package (Top View)
Table 5-1 Pin Functions, TPS628610, TPS628600, TPS628603, TPS628604, TPS628605, and TPS628606
PIN TYPE DESCRIPTION
NAME NO.
GND D2 PWR GND supply pin. Connect this pin close to the GND terminal of the input and output capacitor.
VOS D1 IN Output voltage sense pin for the internal feedback divider network and regulation loop. This pin also discharges VOUT by an internal MOSFET when the converter is disabled. Connect this pin directly to the output capacitor with a short trace.
VIN C2 PWR VIN power supply pin. Connect the input capacitor close to this pin for best noise and voltage spike suppression. A ceramic capacitor is required.
SW C1 PWR The switch pin is connected to the internal MOSFET switches. Connect the inductor to this terminal.
VSEL B2 IN Voltage selection pin. Can be toggled during operation. LOW = 0.6 V (TPS628600, TPS628610), 1.05 V (TPS628603), HIGH = 1.1 V (TPS628600, TPS628610), 0.65 V (TPS628603)
EN B1 IN A high level enables the devices and a low level turns the device off. The pin features an internal pulldown resistor, which is disabled after the device has started up.
SDA A2 IN I2C serial data pin. Do not leave floating.
SCL A1 IN I2C serial clock pin. Do not leave floating.
