Product Overview
The TPS60403 is a Texas Instruments charge pump voltage inverter for Power_Management designs that need an unregulated negative voltage from a positive input supply. The OUT pin provides an output voltage specified as -VI, and the device belongs to the TPS6040x family of inverting charge pumps.
Electrical limits include a 1.6 V to 5.5 V input voltage range, with recommended operation from 1.8 V to 5.25 V. Output current is specified at 60 mA maximum under recommended operating conditions and electrical characteristics, while the absolute maximum continuous output current rating is 80 mA.
For TPS60403, the internal switching frequency is 150 kHz minimum, 250 kHz typical, and 300 kHz maximum. Typical output ripple is 15 mVpp at 5 mA with 1 uF flying and output capacitors. A typical complete converter uses three 1 uF ceramic capacitors and occupies 50 mm2 in the 5-pin SOT-23 package.
