BPA8504D Datasheet | BPS

Integrated Energy Efficient Off-line Switcher IC Description Features The BPA8504D is a high-performance switcher integrated - Integrated 700V power MOSFET circuits with low standby consumption. The BPA8504D can be easily configured as buck, buck-boost, or flyback topologies for universal AC inputs. The BPA8504D integrates a 700V power MOSFET, a high- l voltage current source for self-biasing, a current sensing circuit, and an advanced controller. External loop tia pensation ponents can be mostly eliminated, which reduces cost and size of overall power systems, and meantime achieves high reliability. The BPA8504D employs advanced multi-mode control n algorithm. As a result, the no-load power consumption and average efficiency of the power systems have been e improved and audible noise is reduced. The BPA8504D Features prehensive protections, fid including short circuit protection (SCP), output over voltage protection (OVP), over load protection (OLP), FB open loop protection, cycle-by-cycle current limit, and over temperature protection (OTP). n The BPA8504D is available for SOP-7 package as shown below. Co SOP-7 package - Integrated high-voltage current source for self-biasing - <100m W no load consumption - Excellent transient response - Low output ripple - Optimized line and load regulation - Reduced audible noise at light load - Adaptive switching frequency, 45k Hz 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 BPS Typical Application...
