LM536023QPWPRQ1 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_out | Regulator switch node that connects to the power inductor; pins 1 and 2 must be connected directly together at the PCB. |
| 2 | SW | power_out | Regulator switch node that connects to the power inductor; pins 1 and 2 must be connected directly together at the PCB. |
| 3 | CBOOT | power_in | Bootstrap supply input for the gate drivers, which requires a high-quality 470 nF capacitor from this pin to SW. |
| 4 | VCC | power_out | Internal 3.15 V regulator output used as supply for internal control circuits; do not connect to any external loads, and a high-quality 3.3 µF capacitor is required from this pin to GND. |
| 5 | BIAS | power_in | Input to the internal voltage regulator that connects to the output voltage point and must not be grounded, with a high-quality 0.1 µF capacitor from this pin to GND. |
| 6 | SYNC | input | Synchronization input used to lock the regulator switching frequency to a system clock; connect to GND when unused and do not float it. |
| 7 | FPWM | input | Mode control input where High selects forced PWM and Low selects auto mode with automatic PFM/PWM transition; do not float this pin. |
| 8 | RESET | output | Open-drain reset output that goes High when power is OK and Low on fault, requires a current-limiting pull-up resistor, and goes Low when EN is Low; RESET pin current is limited to 1 mA maximum in recommended operating conditions. |
| 9 | FB | input | Feedback input that connects to the output voltage sense point for fixed 5 V and 3.3 V options or to the feedback divider tap for the ADJ option; do not float or ground this pin. |
| 10 | AGND | power_in | Analog ground for the regulator and system to which all electrical parameters are referenced; connect to EP and PGND on the PCB. |
| 11 | EN | input | Enable input where High turns the regulator ON and Low turns it OFF; it can be connected directly to VIN and must not be left floating. |
| 12 | VIN | power_in | Input supply to the regulator that requires a high-quality bypass capacitor to PGND; pins 12 and 13 must be connected directly together at the PCB. |
| 13 | VIN | power_in | Input supply to the regulator that requires a high-quality bypass capacitor to PGND; pins 12 and 13 must be connected directly together at the PCB. |
| 14 | N/C | unconnected | No connection to the device. |
| 15 | PGND | power_in | Power ground for the internal low-side MOSFET that connects to AGND and system ground; pins 15, 16 and PGND must be connected directly together at the PCB. |
| 16 | PGND | power_in | Power ground for the internal low-side MOSFET that connects to AGND and system ground; pins 15 and 16 must be connected directly together at the PCB. |
| 17 | EP | power_in | Exposed die attach paddle that must connect to the ground plane for adequate heat sinking and noise reduction. |
