... Soft−Start and built in adaptive nonoverlap. The CS5211 also provides adjustable fixed frequency range of 150 kHz to 750 kHz. This gives the designer more flexibility to make efficiency and component size compromises. The CS5211 will operate over a 4 range using either single or dual input voltage. Features • ...

... Startup If there are no fault conditions and the fault latch is reset, the error amplifier will start charging the COMP pin capacitor after the CS5211 is powered up. The output of the 2 error amplifier (COMP voltage) will ramp up linearly. The COMP capacitance and the source current of the error amplifier determine the slew rate of COMP voltage ...

... Remote Voltage Sensing The CS5211 has the capability to sense the voltage when the load is located far away from the regulator. The SGND pin is dedicated to the differential remote sensing. The negative remote sense line is connected to SGND pin directly, while the positive remote sense line is usually connected to the top of the feedback voltage divider ...

APPLICATIONS AND COMPONENT SELECTION Inductor Component Selection The output inductor may be the most critical component in the converter because it will directly effect the choice of other components and dictate both the steady−state and transient performance of the converter. ...

... FFB The negative remote sense connection is provided by connecting the SGND of the CS5211 to the negative of the load return. Again, a low value resistor should be connected between SGND and LGND at the regulator to provide feedback in the instance when the remote sense point is not connected ...

... Low ESR at the regulator output results in low output voltage ripple. This situation could result in increase noise sensitivity and a potential for loop instability. In applications where the output ripple is not sufficient, the performance of the CS5211 can be improved by adding a fixed amount external ramp compensation to the V FFB 7, the amount of ramp at the V ...
