TPS61027DRCR from Texas Instruments, in a VSON-10-EP(3x3). 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 | EN | input | Enable input. Drive to VBAT to enable the device; drive to GND to disable (shutdown). Input high >= 0.8 x VBAT, input low <= 0.2 x VBAT. Input current <= 0.1 uA. |
| 2 | VOUT | power_out | Boost converter output. Regulated to 5.0 V (fixed) on TPS61027. Connect the output capacitor between VOUT and PGND. |
| 3 | FB | input | Voltage feedback input, used by adjustable versions. On the fixed-output TPS61027 this pin is typically tied to the internal reference/output as per the datasheet; for adjustable versions it accepts a resistor-divider tap with a 500-mV (typ) reference. |
| 4 | LBO | output | Low-battery comparator output (open drain). Requires an external pull-up to VBAT or VOUT. VOL <= 0.4 V at IOL = 100 uA; leakage <= 0.1 uA at VLBO = 7 V. |
| 5 | GND | power_in | Control / logic (analog) ground. Reference for control-stage circuitry. |
| 6 | VBAT | power_in | Supply voltage (battery input) for the control stage. Operating range 0.9 V to 6.5 V after start-up; minimum start-up voltage 0.9 V (typ, 1.2 V max) with RL = 120 ohm. |
| 7 | LBI | input | Low-battery comparator input (comparator enabled with EN). Compared against a 500-mV (typ) internal reference with 10-mV hysteresis. May NOT be left floating: tie to GND or VBAT if the comparator is unused. |
| 8 | PS | input | Power-save mode enable/disable. Drive to VBAT to disable power-save mode (forced fixed-frequency PWM); drive to GND to enable power-save mode for improved light-load efficiency. |
| 9 | SW | input | Boost and rectifying switch node. Connect the boost inductor between VBAT and SW. Internal switches: SWN Rds(on) ~260 mOhm, SWP Rds(on) ~290 mOhm. Peak switch current limited to 1800 mA (typ) on TPS61027. |
| 10 | PGND | power_in | Power ground for the internal synchronous rectifier and switch. Return for the output capacitor. The exposed PowerPAD should be soldered to this net. |
| 11 | PowerPAD | passive | Exposed thermal pad on the underside of the VSON-10 package. Must be soldered to the PCB to achieve appropriate power dissipation. Connect to PGND. |
