MRF209

The MRF209 are CMOS charge-pump voltage converters in ultra-small 5-Pin SOMRF209-23A packages. MRF209 invert and/or double an input voltage which can range from +1.5V to +5.5V. Conversion efficiency is typically >95%. Switching frequency is 12kHz for the MRF209. External component requirement is only two capacitors (3.3µF nominal) for standard voltage inverter applications. With a few additional components a positive doubler can also be built. All other circuitry, including control, oscillator, power MOSFEMRF209s are integrated on-chip.
