preliminary datasheet high voltage green mode pwm co ntroller ap3107/h sep. 2011 rev. 1. 0 bcd semiconductor manufacturing limited 1 general description the ap3107/h series is the high voltage start-up, current mode pwm controller with green mode power-saving operation. to minimize the standby power consumption, a proprietary adaptive green mode function provides frequency modulation at light load conditions. to avoid acoustic noise problems, the minimum pwm frequency is set at about 26khz. the ap3107/h series features proprietary frequency dithering function internally that helps to reduce emi emission of a power supply with minimum line filters used. the ap3107/h also integrates a lot of functions such as leading-edge blanking (leb) of the current sensing, internal slope compensation, line compensation and several protection features. the protection functions includ e cycle-by-cycle current limit (ocp), over voltage protection, otp, olp and brownout protection. the ap3107/h series is ava ilable in soic-7 package. features ? high-voltage start-up circuit ? low start-up current: 15 a max. ? fixed oscillation frequency: 65khz (ap3107) 130khz (ap3107h) ? ultra low standby power application ? non-audible-noise green mode control ? leb (leading-edge blanking) on sense pin ? soft driving ? fast ocp for abnormal short circuit ? frequency linearly decreasing at light load ? internal slope compensation ? programmable brownout protection ? useful pin fault protections sense, fb, bno pins floating fb short to ground ? comprehensive system protections 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 ap3107/h soic-7
