preliminary datasheet high voltage green mode pwm controller ap3106 sep. 2011 rev. 1. 0 bcd semiconductor manufacturing limited 1 general description the ap3106 is a high voltage start-up, current mode pwm controller with green-mode power-saving operation. the pwm switching frequency at normal operation is externally programmable and trimmed to a narrow range. the ap3106 integrates a proprietary internal frequency dithering function that helps to reduce emi emission of a power supply with minimum line filters used. to minimize the standby power consumption, a proprietary adaptive green-mode function is available to implement frequency modulation under light-load conditions. to avoid acoustic noise problems, the minimum pwm frequency is set at about 26khz. the ap3106 integrates a lot of functions such as the lead-edge blanking (leb) of the current sensing, internal slope compensatio n, line compensation, and several protection features that include cycle-by-cycle current limit (ocp), over voltage protection, otp, olp and brownout protection. the ap3106 is available in soic-7 package to realize a compact size. features ? high-voltage start-up circuit ? low start-up current: 15 a (max.) ? current mode control ? programmable pwm switching frequency ? non-audible-noise green mode control ? leb (leading-edge blanking) on sense pin ? fast ocp for abnormal short circuit ? frequency linearly decreasing at light load ? soft driving ? internal slope compensation ? built-in brownout protection ? useful pin fault protection cs pin floating ri pin short to ground ri pin floating ? comprehensive system protection vcc over voltage pr otection (vovp) over temperature protection (otp) constant over load protection (colp) short circuit protection (scp) ? compact size soic-7 package applications ? switching ac/dc adaptor ? lcd monitor/tv power ? open frame switching power supply figure 1. package type of ap3106 soic-7
