BP85928D

The BP85928D is a high performance, highly integrated power supply switcher IC with low standby consumption.

The BP85928D can be configured as buck, buck-boost topologies for universal 85~265V AC inputs.

The BP85928D integrates a 650 V power MOSFET, a high- voltage current source for self-biasing, a current sensing circuit, an output feedback circuit, and an advanced controller. External loop compensation components can be eliminated, which reduces cost and size of overall power systems, and improves reliability.

The BP85928D employs multi-mode control algorithm. As a result, the no-load power consumption and the average efficiency have been improved, and the audible noise is reduced.

The BP85928D 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 BP85928D is available in SOP-8 package.
