a set-oscillator, used to precisely control the duty cycle, there is a temperature-compensated reference voltage, a high-gain error amplifier, current sensing comparator and a suitable driving power tube MOSFE high current push-pull output. CS5101 is a bipolar secondary side of the final stage of the regulator, the regulator accuracy up to 1.0%, the gate drive voltage of 8.0 ~ 75V, operating voltage (Ucc) is 8.0 ~ 45V, has a peak output current of 1.5A. There is a precision of 2.0% over the compensated precision voltage reference and error amplifier chip.
