Texas Instruments · Power Management - Specialized · VQFN-32-EP(5x5)

LP87702DRHBTQ1 from Texas Instruments, in a VQFN-32-EP(5x5). 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 nINT output Open-drain interrupt output that is pulled low when a flag is set and is active LOW.
2 FB_B0 input Output voltage feedback input for Buck0.
3 FB_B1 input Output voltage feedback input for Buck1.
4 AGND power_in Analog ground pin.
5 VANA power_in Supply voltage for analog and digital blocks that must be connected to the same node as VIN_Bx, with a recommended range of 2.8 V to 5.5 V.
6 WD_RESET output Reset output from the window watchdog.
7 WDI input Digital input signal for the window watchdog.
8 VOUT_BST power_out Boost converter output, which is also the bypass switch output when that mode is selected.
9 SW_BST power_in Boost input, which is also the bypass switch input when that mode is selected.
10 PGND_BST power_in Power ground for the boost converter.
11 NRST input Reset signal for the device.
12 GPO0 output General purpose digital output 0.
13 VIN_B1 power_in Input for Buck1; the VIN_Bx pins are not connected together internally and must be tied together in the application and locally bypassed.
14 VIN_B1 power_in Input for Buck1; the VIN_Bx pins are not connected together internally and must be tied together in the application and locally bypassed.
15 SW_B1 power_out Buck1 switch node.
16 SW_B1 power_out Buck1 switch node.
17 PGND_B1 power_in Power ground for Buck1.
18 PGND_B1 power_in Power ground for Buck1.
19 EN1 input Programmable Enable 1 signal.
20 SCL input Serial interface clock input for I2C access that requires a pullup resistor and is alternatively programmable as the enable 2 signal.
21 SDA bidirectional Serial interface data input and output for I2C access that requires a pullup resistor and is alternatively programmable as the enable 3 signal.
22 CLKIN bidirectional External clock input for synchronization, with alternative functions of general purpose digital output 2 (GPO2) and watchdog disable (WD_DIS).
23 PGND_B0 power_in Power ground for Buck0.
24 PGND_B0 power_in Power ground for Buck0.
25 SW_B0 power_out Buck0 switch node.
26 SW_B0 power_out Buck0 switch node.
27 VIN_B0 power_in Input for Buck0; the VIN_Bx pins are not connected together internally and must be tied together in the application and locally bypassed.
28 VIN_B0 power_in Input for Buck0; the VIN_Bx pins are not connected together internally and must be tied together in the application and locally bypassed.
29 PG0 output Programmable power-good indication signal.
30 VMON1 input Voltage monitoring input 1.
31 VMON2 input Voltage monitoring input 2.
32 PG1 output Programmable power-good indication signal, with alternative function of general purpose digital output 1 (GPO1).
33 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
