LM53602AQPWPTQ1 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 | SW | power_in | Regulator switch node for power inductor connection; connect pins 1 and 2 directly at PCB. |
| 2 | SW | power_in | Regulator switch node for power inductor connection; connect pins 1 and 2 directly at PCB. |
| 3 | CBOOT | power_in | Bootstrap supply input for gate drivers; connect high quality 470 nF capacitor to SW. |
| 4 | VCC | power_out | Internal 3.15 V regulator output for internal control circuits; do not connect to external loads. |
| 5 | BIAS | power_in | Input to internal voltage regulator connected to output voltage point; do not ground. |
| 6 | SYNC | input | Synchronization input to regulator for system clock frequency synchronization; connect to GND when not used. |
| 7 | FPWM | input | Mode control input selecting forced PWM (high) or auto PFM/PWM mode (low). |
| 8 | RESET | output | Open drain reset output; high indicates power OK, low indicates fault. |
| 9 | FB | input | Feedback input for output voltage sense (fixed modes) or feedback divider tap (ADJ mode); do not float or ground. |
| 10 | AGND | power_in | Analog ground for regulator and system; all electrical parameters measured with respect to this pin. |
| 11 | EN | input | Enable input to regulator; high enables operation, low disables operation; can connect directly to VIN. |
| 12 | VIN | power_in | Input supply to regulator (3.9 V to 36 V) with high quality bypass capacitor(s) to PGND; connect pins 12 and 13 directly at PCB. |
| 13 | VIN | power_in | Input supply to regulator (3.9 V to 36 V) with high quality bypass capacitor(s) to PGND; connect pins 12 and 13 directly at PCB. |
| 14 | N/C | unconnected | No connection to device. |
| 15 | PGND | power_in | Power ground for internal low side MOSFET; connect to AGND and system ground; connect pins 15 and 16 directly at PCB. |
| 16 | PGND | power_in | Power ground for internal low side MOSFET; connect to AGND and system ground; connect pins 15 and 16 directly at PCB. |
| 17 | EP | power_in | Exposed die attach paddle for adequate heat sinking and noise reduction; connect to ground plane. |
