Design a Custom BoardAbout This Component
Charge pump voltage inverter IC that generates a negative output voltage from a positive input supply. Delivers up to 40mA output current with typical inversion ratios of -1x. Integrates all required switching circuitry and oscillator for compact single-chip implementation. Commonly used in audio circuits, RS-232 level shifting, and LCD bias supply applications.
Package: SOT-23-6 · 6 pins
Why does this need a breakout?
SOT-23-6 packages house precision regulators, voltage references, and level shifters with 0.95mm pin pitch—too fine for hand soldering and incompatible with breadboards. A breakout board provides through-hole headers for prototype work, eliminating soldering difficulty while enabling quick circuit iteration. Essential for developing with compact analog and power management ICs.
