Output voltage: invert, double, or halve the input
The TPS60403DBVRG4 is a ratiometric charge pump from Texas Instruments that generates a fixed output voltage equal to -Vin, 2Vin, or Vin/2, depending on the external circuit configuration. This means a single part can produce a negative rail, a boosted positive rail, or a divided rail from the same input supply — useful when a design needs a secondary voltage without adding an inductor.
60 mA output — sizing the load budget
Rated for 60 mA continuous output, this charge pump suits low-current rails such as op-amp supplies, sensor bias, or small logic-level translators. The 250 kHz switching frequency keeps the external flying capacitor small — typically 0.22 µF to 1 µF ceramic — which saves board area. The single output channel is unregulated and follows the input ratio, so the load current must stay within the 60 mA ceiling and the input source must handle the peak switch current.
Temperature range and package — where it fits
The SOT-23-5 package (SC-74A, SOT-753) occupies about 3 mm² of board area and is a common footprint for space-constrained designs. Surface-mount assembly is standard; no special reflow profile beyond the usual lead-free solder process.
