Product details

Charge pump for automotive rails

The Texas Instruments TPS60403QDBVRQ1 is an automotive-grade (AEC-Q100) switched-capacitor charge pump in a SOT-23-5 package. The 250 kHz switching frequency keeps the external flying capacitors small enough for a compact PCB layout.

Output configuration and load budget

The single-output ratiometric topology can be wired as a positive doubler, an inverter, or a split-rail divider — no inductor needed. The 60 mA rating is continuous; at elevated ambient the SOT-23-5's junction-to-ambient thermal resistance will limit usable current, so budget derating above 85°C case temperature. The synchronous rectifier is disabled internally, so the output is unregulated and tracks the input ratio.

Frequently asked questions

Can TPS60403QDBVRQ1 generate a negative voltage?

Yes — the output configuration supports positive or negative output. Wired as an inverter, it produces -Vin from a positive input rail up to 5.25 V.

What is the difference between TPS60403QDBVRQ1 and TPS60400QDBVRQ1?

Both are charge pumps in the same SOT-23-5 footprint, but the TPS60403 is a fixed-output ratiometric device while the TPS60400 is adjustable. The TPS60403 gives you -Vin, 2Vin, or Vin/2 without external feedback resistors; the TPS60400 uses an external divider to set the output.
