Introduction
The RT9397BF is a highly integrated step-up charge pump and inverting charge pump to generate positive and negative output voltage. The output voltages can be adjusted from ±4.5V to ±6V through external feedback resistors. The part maintains highest efficiency by utilizing a ×1.33/×1.5/×1.75/×2 mode fractional charge pump with automatic mode transition. The RT9397BF is available in a WQFN-20L 3x3 package to achieve optimized solution for PCB space.
Features
- 2.7V to 4.5V Supply Voltage Range
- Over 80% Average Efficiency of Battery Life
- Support up to 50mA Output Current
- Low 1μA Shutdown Current
- Internal Soft-start Function
- Short Circuit Protection Function
- Over-Voltage Protection Function
