Application Information

The FC6160 is a high voltage, low dropout linear regulator that could provide 150mA output current at 800mV dropout voltage. Besides, current limit and on chip thermal shutdown features provide protection against any combination of overload or ambient temperature that could exceed junction temperature. Shutdown Control Force /SHDN pin high to enable the FC6160 and turned off the device by pulling it low. The /SHDN pin can’t be floated and must be tied to the VIN if not used. Output Voltage Setting The output voltage of regulator is determined by connecting external resistor dividers. The external resistor divider connects with FB pin. The output voltage is determined by the following equation: 235 . 1R R1 VR R RV FB 2 1 OUT × + = ×+= PSRR (Power Supply Rejection Ratio) The FC6160 has high 65dB PSRR. Ripple rejection is the ability of the regulator to reduce input voltage ripple. It is specified with a 120Hz and 1V P-P signal applying to input, with 1uF output capacitor. Ripple rejection, expressed in dB, is the ratio of output ripple to input ripple. Output and Input Capacitor The FC6160 is designed to be stable with low ESR ceramic capacitors. Higher values of capacitors and ESR could improve output stability. So the ESR of output capacitor is very important because it generates a zero to provide phase lead for loop stability. It is recommended to use 1uF to 10uF X5R or X7R dielectric ceramic capacitors with 30mΩ to 50mΩ ESR range between VOUT and GND for transient stability. Larger value of the output capacitor decreases the peak deviations and provides to improve transition response for larger current changes. The ESR is not essential for input capacitor, but its voltage and temperature coefficient have to be considered for device application environment. Over Temperature Protection Over temperature protection function is integrated in the chip. The thermal protection function prevents the excessive power dissipation form overheating. When the chip temperature is higher than 150° C, the controller is shutdown. When the junction temperature cools down to a constant value, the thermal protection is released and the chip operates normal again. Thermal Consideration The power hand ling capability of the device will be limited by allowable operation junction temperature (125 °C). The power dissipated by the device will be estimated by P D = IOUT × (VIN-VOUT). The power dissipation should be lower than the maximum power dissipation listed in “Absolute Maximum Ratings” section.
