Application Information

The FP6121 include 2 independent output channels. Current limit and on chip thermal shutdown features provide protection against any combination of overload or ambient temperature that could exceed maximum junction temperature. EN Control Force EN pin high to enable the FP6121 and turned off the device by pulling it low. The E pin can’t be floated and must be tied to the Vin if not used. The enable control is independent to each channel. PSRR (Power Supply Rejection Ratio) The FP6121 has high 70dB PSRR. Ripple rejection is the ability of the regulator to reduce input voltage ripple. It is specified with a 1 0kHz and 1VP-P signal applying to input, with 1μF output capacitor. Ripple rejection, expressed in dB, is the ratio of output ripple to input ripple. Thermal Shutdown Thermal shutdown is employed to protect the device damage from the junction temperature exceed safe margins due mainly to short circuit or current limit. Moreover, the device returns normally operation when t he junction temperature down to a constant temperature. Though temperature protection circuit is built in to protect IC, the maximum power dissipation design within Tj(max) is needed. The thermal protection is independent to each channel. Thermal Consideration The power handling capability of the device will be limited by maximum 125 C operation junction temperature. The power dissipated by the device will be estimated by PD = IOUT  (VIN-VOUT) The power dissipation should be lower than the maximum power dissipation listed in “Absolute Maximum Ratings” section. Capacitor Selection The ceramic capacitor is ideal for FP6121 application. The ESR of the output capacitor affects stability. Larger value of the output capacitor decreases the peak deviations and improves transient response for larger current changes. The capacitor types (ceramic, aluminum, and tantalum) have different characterizations such as voltage and temperature coefficients. All ceramic capacitors are manufactured with a vari ety of dielectrics, each with different behavior across temperature and applications. Common dielectrics used are X5R, X7R and Y5V. It is recommended to use 1 μF to 10μF X5R or X7R dielectric ceramic capacitors because X5R or X7R hold their capacitance ove r wide voltage and temperature ranges than other Y5V or Z5U types. The ESR of output capacitor is very important because it generates a zero to provide phase lead for loop stability. The input capacitor can reduced peak current and noise at power source.
