Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SYNC | input | Synchronization input for locking the switching frequency to an external clock between 200 and 530 kHz; connect to GND if unused. Absolute range is -0.3 V to 5.5 V (6.2 V for t < 10 s). |
| 2 | GND | power_in | Ground reference for all voltages; the exposed pad must also be connected to GND and the heatsink area by low-inductance wiring. |
| 3 | COMP | input | Compensation input for regulation loop stability; connect an RC compensation network to GND, as leaving it open may cause unstable operation. Absolute range is -0.3 V to 5.5 V (6.2 V for t < 10 s). |
| 4 | FB | input | Feedback input; the TLE8366EV connects it through a voltage divider and the fixed versions connect it directly to the output capacitor. Absolute range is -0.3 V to 10 V for TLE8366EV50/EV33 and -0.3 V to 5.5 V for TLE8366EV. |
| 5 | BDS | power_in | Buck driver supply input for the bootstrap capacitor, which connects between this pin and BUO. Absolute range is VBUO - 0.3 V to VBUO + 5.5 V. |
| 6 | BUO | output | Buck switch output, the source of the integrated power DMOS, which connects directly to the catch diode cathode and buck inductance. Absolute range is -2.0 V to VS + 0.3 V. |
| 7 | EN | input | Active-high enable input with integrated pull-down; high is valid from 3.0 V and low is valid up to 0.8 V, with an absolute range of -40 V to 45 V. |
| 8 | VS | power_in | Supply voltage input with a functional range of 4.75 V to 45 V and an absolute maximum range of -0.3 V to 45 V. |
