LM26480SQ-AA

Texas Instruments · DC-DC Converters · WQFN-24-EP(4x4)

LM26480SQ-AA from Texas Instruments, in a WQFN-24-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VINLDO12 power_in Analog power supply for internal functions (VREF, BIAS, I2C, Logic)
2 SYNC input Frequency synchronization pin allowing external clock signal to synchronize PMIC internal oscillator; must be grounded when not used
3 nPOR output Power on reset pin for Buck1 and Buck2 with open drain logic output and 100-kΩ pullup resistor; pulled to ground when supply voltages not good
4 GND_SW1 power_in Buck1 NMOS power ground
5 SW1 power_out Buck1 switcher output pin
6 VIN1 power_in Power input for Buck1 from either DC source or battery
7 ENSW1 input Enable pin for Buck1 switcher; logic HIGH enables Buck1; pin cannot be left floating
8 FB1 input Buck1 feedback input terminal
9 GND_C power_in Non-switching core ground pin
10 AVDD power_in Analog power supply for Buck converters
11 FB2 input Buck2 feedback input terminal
12 ENSW2 input Enable pin for Buck2 switcher; logic HIGH enables Buck2; pin cannot be left floating
13 VIN2 power_in Power input for Buck2 from either DC source or battery
14 SW2 power_out Buck2 switcher output pin
15 GND_SW2 power_in Buck2 NMOS power ground
16 ENLDO2 input Enable pin for LDO2; logic HIGH enables LDO2; pin cannot be left floating
17 ENLDO1 input Enable pin for LDO1; logic HIGH enables LDO1; pin cannot be left floating
18 GND_L power_in LDO ground pin
19 VINLDO1 power_in Power input for LDO1 from either DC source or battery
20 LDO1 power_out LDO1 output voltage
21 FBL1 input LDO1 feedback input terminal
22 FBL2 input LDO2 feedback input terminal
23 LDO2 power_out LDO2 output voltage
24 VINLDO2 power_in Power input for LDO2 from either DC source or battery
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
