TSM1052 from STMicroelectronics, in a SOT-23-6. 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 | Vctrl | input | Inverting input of the voltage control loop operational amplifier, connected to the feedback voltage divider sensing the output voltage. |
| 2 | GND | power_in | Ground reference for all voltages and return path for device bias current. |
| 3 | OUT | output | Open-drain output capable of sinking up to 100 mA, transmitting error signal from both voltage and current control loops to the optocoupler. |
| 4 | Ictrl | input | Non-inverting input of the current control loop operational amplifier, connected directly to the current sense resistor. |
| 5 | Vsense | input | Inverting input of the current control loop operational amplifier, connected to the current sense resistor through a decoupling resistor with internal reference at -200 mV. |
| 6 | Vcc | power_in | Supply voltage input with operating range from 1.7 V to 18 V, requiring a 0.1 µF bypass capacitor to ground. |
