Resonant Mode Power Supply Controller

The UC1860 family of control ICs is a versatile system for resonant mode power supply control. This device easily implements frequency modulated fixed-on-time control schemes as well as a number of other power supply control schemes with its various dedicated and programmable features. The UC1860 includes a precision Voltage Reference a wide-bandwidth er- ror Amplifier a variable frequency Oscillator operable to beyond 3MHz, an oscillator-triggered one-shot, dual high-current totem-pole output drivers, and a programmable toggle Flip-Flop The output mode is easily pro- grammed for various sequences such as A, off, B, off; A & B, off; or A, B, off. The error Amplifier contains precision output clamps that allow pro- gramming of minimum and maximum frequency. The device also contains an uncommitted Comparator a fast Comparator for fault sensing, programmable soft start circuitry, and a programmable restart delay. Hic-up style response to faults is easily achieved. In addi- tion, the UC1860 contains programmable under voltage lockout circuitry that forces the output stages low and minimizes supply current during start-up conditions. By Texas Instruments
