Texas Instruments · DC-DC Converters · WSON-10-EP(3x3)
LM536003QDSXRQ1 from Texas Instruments, in a WSON-10-EP(3x3). 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 | tri_state | Regulator switch node connected to output inductor; driven high by high-side FET and pulled low by low-side FET. |
| 2 | BOOT | power_in | High side gate driver upper supply rail; connect 100-nF capacitor from SW to BOOT; internal diode charges capacitor when SW node is low. |
| 3 | VCC | power_out | Internal 3-V regulator output used as supply to internal control circuits; connect 1.0-μF high-quality capacitor from this pin to AGND. |
| 4 | FB | power_in | Fixed version feedback pin for output voltage and power source for VCC regulator; connect to output node and place 10-nF bypass capacitor immediately adjacent. |
| 5 | AGND | power_in | Fixed version signal and feedback ground to which input signals and FB are compared. |
| 6 | RESET | output | Open drain reset output; high = regulator OK, low = regulator fault; goes low when EN pin is low; connect through current-limiting pull-up resistor to suitable voltage supply. |
| 7 | EN | input | Enable input to regulator; high = on, low = off; can be connected to Vin; do not float. |
| 8 | VIN | power_in | Input supply to regulator operating from 3.8V to 36V; connect input bypass capacitors directly between this pin and GND. |
| 9 | SYNC/MODE | input | Multifunction mode control input tolerant of voltages up to input voltage; with valid synchronization signal enables forced PWM mode at external clock frequency; with high enforces PWM mode; with low enables AUTO mode with diode emulation at light load; do not float. |
| 10 | GND | power_in | Power and signal ground connection; bypass to VIN immediately adjacent to this pin. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
