ansformers and RCC SMPS. The FEZ1307 is designed to work using few external components offering many other features like : low standby power: under 30mW, high-voltage startup, constant-voltage (CV) and constant-current (CC) control without secondary-feedback circuitry, fixed PWM frequency at 50kHz with frequency hopping to solve EMI problem, cable compensation in CV mode, peak-current-mode control in CV mode, cycle-by-cycle current limiting, VDD over-voltage protection with auto restart, VDD under-voltage vockout (UVLO), gate output maximum voltage clamped at 15V, fixed over-temperature protection with auto restart.
