RC4391 - Inverting And Step-down Switching Regulator
Fairchild Semiconductor’s RC4391 is a monolithic switch mode power supply controller for micropower circuits.
The RC4391 integrates all the active functions needed for low power switching supplies, including oscillator, switch, reference and logic, into a small package.
Also, the quiescent supply cu
