BPA8505D Integrated Energy Efficient Off-line Switcher IC Description Features The BPA8505D is a high performance, highly integrated - Integrated 700V power MOSFET power supply switcher IC with low standby consumption. - Integrated high-voltage current source for self- The BPA8505D can be configured as buck, buck-boost, or flyback topologies for universal 85~265V AC inputs. The BPA8505D integrates a 700 V power MOSFET, a highvoltage current source for self-biasing, a current sensing l circuit, and an advanced controller. External loop pensation ponents can be mostly eliminated, tia which reduces cost and size of overall power systems, and meantime achieves high reliability. The BPA8505D employs advanced multi-mode control algorithm. As a result, the no-load power consumption n and average efficiency of the power systems have been improved and audible noise is reduced. e The BPA8505D Features prehensive protections, including short circuit protection (SCP), output over fid voltage protection (OVP), over load protection (OLP), cycle-by-cycle current limit, and over temperature protection (OTP). Con The BPA8505D is available in SOP-7 packages. biasing - <100mW no load consumption at 230VAC - Excellent transient response - Low output ripple - Optimized line and load regulation - Reduced audible noise at light load - Adaptive switching frequency, 45kHz maximum - Frequency modulation for EMI improvement - Internal soft start - prehensive protections - Short circuit protection (SCP) - Over voltage protection (OVP) - Over load protection (OLP) - Cycle-by-cycle current limit - Over temperature protection (OTP) Applications - Home appliances - Motor driver standby power supply - IoT, smart home, smart LED drivers - Industrial controls...
