Power converter with compensation circuit for adjusting output current provided to a constant load.

UC from Texas Instruments

Primary side feedback FB switching power supply controller and switching power supply system. According to the switch power supply circuit based on UC, output voltage feedback of voltage type control can be set up, current feedback of an inductance coil is increased, and the current feedback is taken as slope parameters of a PWM control convertor, so that a sawtooth generator is not needed, the system response speed is rapid, the linear adjusting rate is high in precision, and the requirement of high precision of voltage-stabilized power supply can be easily met.
