The BPA8505D is a high performance, highly integrated power supply switcher IC with low standby consumption.
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 high- voltage current source for self-biasing, a current sensing circuit, and an advanced controller. External loop compensation components can be mostly eliminated, 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 and average efficiency of the power systems have been improved and audible noise is reduced.
The BPA8505D features comprehensive protections, including short circuit protection (SCP), output over voltage protection (OVP), over load protection (OLP), cycle-by-cycle current limit, and over temperature protection (OTP).
The BPA8505D is available in SOP-7 packages.
