Features
SIMPLE SWITCHER®
power converter using integrated FET in inverting buck-boost configuration
Cost-effective inverter using just a single inductor and a standard buck device
Sinusoidal input and output ripple reduces conducted emissions
Clean waveforms (no ringing, no overshoot) prevents FM band noise
