Abstract :
A novel integrated circuit, the UC1860, is introduced. Its prime purpose is to provide the control function in resonant mode power supplies operating at frequencies up to 3 MHz. A frequency-modulated, fixed on-time control scheme is implemented. Additional features include a programmable under-voltage lockout circuit and a programmable soft-start/hiccup circuit
