TPS63060

@@ -0,0 +1,54 @@+# TPS63060++**Texas Instruments** · Buck-boost converter · WSON-10++Holds a regulated output whether the input is above or below it, so a battery that sags through the target voltage still delivers a steady rail. It runs from 2.5 to 12 V, switches at up to 2.4 MHz with 2 A integrated switches, and a resistor divider at FB sets the output, with a power-save mode for light-load efficiency. A PS/SYNC pin picks the switching mode. Common where a Li-ion or multi-cell pack must make a fixed 3.3 or 5 V across its whole discharge.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | L1 | passive | Connection for the external power inductor between the VIN-side switch node and the buck-boost inductor. Absolute max -0.3 V to 17 V (AC transients -5 V to 18 V for <10 ns). |+| 2 | VIN | power_in | Supply voltage for the power stage. Recommended operating range 2.5 V to 12 V; absolute max 17 V. Bypass with CIN to GND close to the pin. |+| 3 | EN | input | Enable input. Logic 1 enables the converter, logic 0 disables it and disconnects the load. VIL max 0.4 V, VIH min 1.2 V. Do not leave floating. |+| 4 | PS/SYNC | input | Power-save mode select and synchronization input. Logic 1 disables power-save (forced fixed-frequency PWM), logic 0 enables power-save mode; can also accept a 2.2-2.6 MHz clock for synchronization. |+| 5 | PG | output | Power-good open-drain output. High (via external pull-up) when VOUT is in regulation; low on failure. VOL 0.04 V typ at 10 uA, leakage 0.01 uA typ. |+| 6 | VAUX | power_out | Internal auxiliary bias rail output; connect a bypass capacitor (CAUX) to GND. Tracks the higher of VIN or VOUT, clamped at 7 V; max load 1 mA. |+| 7 | GND | power_in | Control and logic ground reference for the analog control circuitry. |+| 8 | FB | input | Feedback input. On the adjustable TPS63060, connect the external resistor divider from VOUT to set output voltage (VFB = 500 mV typ, 2.5-8 V range). On the fixed TPS63061 this pin must be tied to VOUT. |+| 9 | VOUT | power_out | Buck-boost converter output. Regulated 2.5 V to 8 V (adjustable) or 5 V (TPS63061); up to 2 A in buck mode (VIN<10 V) or 1.3 A in boost mode (VIN>4 V). Bypass with COUT. |+| 10 | L2 | passive | Connection for the external power inductor between the VOUT-side switch node and the buck-boost inductor. Absolute max -0.3 V to 17 V (AC transients -5 V to 18 V for <10 ns). |+| 11 | PGND | power_in | Exposed thermal pad on the package underside. Must be soldered to the PCB for adequate power dissipation and must be connected to PGND (power ground plane). |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Buck-boost (step up/down) converter |+| Input | 2.5-12 V |+| Output | Adjustable (above or below input) |+| Switch current | 2 A |+| Switching freq | Up to 2.4 MHz |+| Light load | Power-save mode (PS/SYNC) |+| Package | WSON-10 |++## Ordering variants++- `TPS63060DSCR (WSON-10)`+- `TPS63061DSCR (fixed output variant)`++## CAD (KiCad official)++- Symbol: `Regulator_Switching:TPS63060 (KiCad official)`+- Footprint: `Package_SON:Texas_S-PWSON-N10_ThermalVias`+- 3D model: WSON-10 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps63060.pdf) (31 pp, sha256 `d2818015ba4b0d7c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
