PIN DESCRIPTION
NAME NO.
EN/UVLO 6 Enable pin. For EN/UVLO < 0.3 V, the TPS25762-Q1 is in a low current shutdown mode. For EN/UVLO > 1.3 V, the full functionality is enabled, provided LDO_5V exceeds the LDO_5V UVLO threshold.
IN 15 The input supply pin to the IC. Connect VIN to a supply voltage between 5.5 V and 18 V (40-V ABS MAX transient).
PGND 13 Power ground of the IC. The high current ground connection to the low-side gate drivers.
SW1 14 The buck side switching node.
SW2 12 The boost side switching node.
BOOT1 16 An external capacitor is required between the BOOT1 and the SW1 pins to provide bias to the high-side MOSFET gate drivers.
BOOT2 10 An external capacitor is required between the BOOT2 and the SW2 pins to provide bias to the high-side MOSFET gate drivers.
AGND 5 Analog ground of the IC.
OUT 11 Output of the buck-boost regulator. Connect to bulk capacitance.
CSP 28 Positive input of the current sense amplifier.
CSN/BUS 29 Negative input of the current sense amplifier. This is the PA_VBUS supply.
LDO_5V 21 Output of internal 5 V LDO for buck-boost low-side FET drivers, and Px_VCONN supply. Connect bypass capacitor to PGND. May be overdriven from external 5-V supply.
LDO_3V3 27 Output of internal 3.3-V LDO for analog circuitry and GPIO drivers. Connect bypass capacitor to AGND.
LDO_1V5 7 Output of internal 1.5-V LDO for digital circuitry. Connect bypass capacitor to AGND.
I2C_SCL1 3 Controller I2C Clock Input/Output.
