RC4391 Description
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 current drawn by the RC4391 is extremely low;.
