Applications

* The RC4391 complements another Fairchild Semiconductor switching regulator IC, the RC4190. The RC4190 is dedicated to step-up (VOUT > VIN) applications, while the RC4391 was designed for inverting (VOUT = -VIN) and step-down (VOUT < VIN) applications. Between the two devices the ability to create a
