# TPS62003DGSR

**Texas Instruments** · DC-DC Converters · VSSOP-10-0.5mm

TPS62003DGSR from Texas Instruments, in a VSSOP-10-0.5mm. 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 | VIN | power_in | Supply voltage input with recommended operating range of 2 V to 5.5 V. |
| 2 | FC | passive | Supply bypass pin; connect 0.1-μF coupling capacitor as close as possible to this pin for good high-frequency input voltage supply filtering. |
| 3 | GND | power_in | Ground reference terminal. |
| 4 | PG | output | Open-drain power good comparator output that goes active high when the output voltage is greater than 92% of the nominal value; requires pull-up resistor to VOUT. |
| 5 | FB | input | Feedback input pin for fixed output voltage option; external resistive divider connected to FB in adjustable version with internal voltage divider disabled. |
| 6 | ILIM | input | Switch current limit pin; connect to GND for typically 600 mA current limit or to VIN for typically 1200 mA current limit. |
| 7 | SYNC | input | External clock synchronization input accepting CMOS levels; logic high enables fixed frequency PWM mode, logic low (GND) enables power save mode with PFM/PWM operation. |
| 8 | EN | input | Enable input; logic high enables the converter, logic low forces shutdown mode with supply current less than 1 μA. |
| 9 | L | bidirectional | Inductor and switch pin connected to the drain of the internal power MOSFETS. |
| 10 | PGND | power_in | Power ground terminal; connect all power grounds to this pin. |
