LM536035QPWPTQ1 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 | output | Regulator switch node with voltage range -0.3 V to VIN+0.3 V; connect pins 1 and 2 together on PCB to power inductor. |
| 2 | SW | output | Regulator switch node with voltage range -0.3 V to VIN+0.3 V; connect pins 1 and 2 together on PCB to power inductor. |
| 3 | CBOOT | power_in | Bootstrap supply input for high-side gate driver with voltage range -0.3 V to 3.6 V; connect 470 nF capacitor to SW. |
| 4 | VCC | power_in | Internal 3.15 V regulator output with voltage range -0.3 V to 4.2 V supplying internal control circuits; connect 3.3 µF capacitor to GND. |
| 5 | BIAS | input | Input to internal LDO voltage regulator with voltage range -0.3 V to 16 V; connect to output voltage with 0.1 µF capacitor to GND. |
| 6 | SYNC | input | Synchronization input to regulator with voltage range -0.3 V to 5.5 V and logic thresholds VIH=1.5 V, VIL=0.4 V; ground when not used. |
| 7 | FPWM | input | Mode control input for forced PWM (high) or auto mode (low) with voltage range -0.3 V to 5.5 V and logic thresholds VIH=1.5 V, VIL=0.4 V. |
| 8 | RESET | output | Open-drain reset output with voltage range -0.3 V to 8 V and maximum 1 mA current; high indicates power OK, low indicates fault or EN low. |
| 9 | FB | input | Feedback input to regulator with voltage range -0.3 V to 16 V (fixed modes) or -0.3 V to 5.5 V (ADJ option); connect to output voltage for fixed or divider tap for ADJ. |
| 10 | AGND | power_in | Analog ground reference with voltage offset ±0.3 V to PGND (±2 V transient tolerance); connect to EP and PGND on PCB. |
| 11 | EN | input | Enable input with voltage range -0.3 V to 40 V; rising threshold 2 V for ON, falling threshold 0.8 V for complete shutdown. |
| 12 | VIN | power_in | Input supply voltage with nominal range 3.9 V to 36 V and 42 V transient peak; connect bypass capacitors to PGND with pins 12 and 13 shorted on PCB. |
| 13 | VIN | power_in | Input supply voltage with nominal range 3.9 V to 36 V and 42 V transient peak; connect bypass capacitors to PGND with pins 12 and 13 shorted on PCB. |
| 14 | N/C | unconnected | No electrical connection to the device. |
| 15 | PGND | power_in | Power ground for internal low-side MOSFET with voltage offset -0.3 V to +0.3 V to AGND; connect pins 15 and 16 together on PCB to system ground. |
| 16 | PGND | power_in | Power ground for internal low-side MOSFET with voltage offset -0.3 V to +0.3 V to AGND; connect pins 15 and 16 together on PCB to system ground. |
| 17 | EP | power_in | Exposed die attach thermal pad for heat sinking and ground connection; connect to ground plane with minimum 4×4 array of 10 mil thermal vias. |
