LM26400YMH from Texas Instruments, in a HTSSOP-16-EP. 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 | FB1 | input | Feedback pin of Channel 1; connect FB1 to an external voltage divider to set the output voltage of Channel 1. |
| 2 | SS1 | input | Soft-start pin of Channel 1; connect a capacitor between this pin and ground to program the start-up speed. |
| 3 | EN1 | input | Enable control input for Channel 1; logic high enables operation, and this pin must not be allowed to float or be greater than VIN + 0.3 V. |
| 4 | AVIN | power_in | Input supply for generating the internal bias used by the entire IC and for the internal bootstrap bias; needs to be locally bypassed. |
| 5 | GND | power_in | Signal and power ground; Kelvin connect the lower resistor of the feedback voltage divider to this pin for good load regulation. |
| 6 | EN2 | input | Enable control input for Channel 2; logic high enables operation, and this pin must not be allowed to float or be greater than VIN + 0.3 V. |
| 7 | SS2 | input | Soft-start pin of Channel 2; connect a capacitor between this pin and ground to program the start-up speed. |
| 8 | FB2 | input | Feedback pin of Channel 2; connect FB2 to an external voltage divider to set the output voltage of Channel 2. |
| 9 | BST2 | output | Supply rail for the gate drive of Channel 2's NMOS switch; a bootstrap capacitor should be placed between BST2 and SW2. |
| 10 | SW2 | output | Switch node of Channel 2; connects to the inductor, catch diode, and bootstrap capacitor. |
| 11 | PVIN | power_in | Input voltage of the power supply, directly connected to the drain of the internal NMOS switch; tie together with pins 12-14 and connect to a local bypass capacitor. |
| 12 | PVIN | power_in | Input voltage of the power supply, directly connected to the drain of the internal NMOS switch; tie together with pins 11, 13 and 14 and connect to a local bypass capacitor. |
| 13 | PVIN | power_in | Input voltage of the power supply, directly connected to the drain of the internal NMOS switch; tie together with pins 11, 12 and 14 and connect to a local bypass capacitor. |
| 14 | PVIN | power_in | Input voltage of the power supply, directly connected to the drain of the internal NMOS switch; tie together with pins 11-13 and connect to a local bypass capacitor. |
| 15 | SW1 | output | Switch node of Channel 1; connects to the inductor, catch diode, and bootstrap capacitor. |
| 16 | BST1 | output | Supply rail for the gate drive of Channel 1's NMOS switch; a bootstrap capacitor should be placed between BST1 and SW1. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
