TPS61085TPWR

Texas Instruments · DC-DC Converters · TSSOP-8

TPS61085TPWR from Texas Instruments, in a TSSOP-8. 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 COMP bidirectional Compensation pin; the external compensation network allows the regulator to be optimized for application conditions.
2 FB input Feedback pin; feedback regulation voltage is 1.230 V to 1.246 V (1.238 V typical).
3 EN input Shutdown control input; connect to a logic high level (2 V minimum, 7 V absolute maximum) to enable the device.
4 PGND power_in Power ground for the boost converter power stage.
5 SW input Switch pin for the integrated 2-A, 0.13-Ω N-channel power MOSFET; absolute maximum voltage is 20 V.
6 IN power_in Input supply pin; input voltage range is 2.3 V to 6 V (7 V absolute maximum).
7 FREQ input Frequency select pin; the switch runs at 650 kHz when FREQ is tied to GND and at 1.2 MHz when tied to IN.
8 SS output Soft-start control pin; connect a capacitor for soft start, or leave open for no soft start.
