This highly integrated controller implements frequency modulation control and complete system functions in only an 8-pin package. Switching to the UCC25600 will greatly simplify the system design and layout, and improve time to market, all at a price point lower than competitive 16pin device offerings. The internal oscillator supports the switching frequencies from 40 kHz to 350 kHz. This hig...
