Linear Regulator Output (VCCL)
The IR3513 has a built-in linear regulator controller, and only an external NPN transistor is needed to create a linear
regulator. The output voltage can be programmed between 4.75V and 7V by the resistor divider at VCCLFB pin.
The regulator output powers the gate drivers of the phase ICs and circuits in the control IC, and the voltage is
usually programmed to optimize the converter efficiency. The linear regulator can be compensated by a 4.7uF
capacitor at the VCCL pin. As with any linear regulator, due to stability reasons, there is an upper limit to the
maximum capacitor value that can be used at this pin and it is a function of the number of phases used in the
multiphase architecture and their switching frequency. Figure 10 shows the stability plots for the linear regulator with
5 phases switching at 750 kHz.
