BP85928D
High Integration Off-line Switcher
Description
Features
The BP85928D is a high performance, highly integrated
Integrated 650V power MOSFET
power supply switcher IC with low standby consumption.
Integrated high-voltage current source for self-
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-
l voltage current source for self-biasing, a current sensing
circuit, an output feedback circuit, and an advanced
tia controller. External loop compensation components can
be eliminated, which reduces cost and size of overall power systems, and improves reliability.
n The BP85928D employs multi-mode control algorithm.
