TSM1012AIDT from STMicroelectronics, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VRef | output | Voltage reference output, 1.25 V typical (0.5% precision for TSM1012A). Maximum output current 2.5 mA. Used to bias the CC/CV loop resistor dividers. |
| 2 | CC- | input | Inverting input of the current-control transconductance operational amplifier. Directly accessible for external compensation network (e.g., Ric1 + Cic1 to OUT). |
| 3 | CC+ | input | Non-inverting input of the current-control transconductance operational amplifier. Tied to the middle point of the R4/R5 divider that sets the Vsense threshold from Vref. |
| 4 | CV- | input | Inverting input of the voltage-control transconductance operational amplifier. Directly accessible for external compensation network (e.g., Rcv1 + Cvc1 to OUT). |
| 5 | CV+ | input | Non-inverting input of the voltage-control transconductance operational amplifier. Fed by the R1/R2 divider on the regulated output to close the voltage loop. |
| 6 | GND | power_in | Ground line. 0 V reference for all voltages on the device. |
| 7 | OUT | output | Common sink output of the two transconductance operational amplifiers (ORed, common-collector). Drives the optocoupler LED cathode; sinks up to ~10 mA short-circuit to (VCC - 0.6 V). Vol = 250 mV typ. at 5 mA sink. |
| 8 | VCC | power_in | Power supply line. Operating range 4.5 V to Vz (28 V internal Zener clamp at ICC = 50 mA). Total supply current 100 µA typ. (180 µA max) excluding Vref load. |
