BP8522D
Ultra-high Integration Off-line Switcher IC
Description
Features
The BP8522D is a high performance, highly integrated ◼ Integrated VCC capacitor, freewheeling diode and
power supply switcher IC with low standby consumption.
feedback diode
The BP8522D can be configured as buck, buck-boost topologies for universal 85~265V AC inputs.
The BP8522D integrates a 550 V power MOSFET, a highvoltage current source for self-biasing, a current sensing
l circuit, an output feedback circuit, a freewheeling diode
and an advanced controller. External VCC capacitor and
tia loop compensation components can be eliminated,
which reduces cost and size of overall power systems, and improves reliability.
The BP8522D employs advanced multi-mode control
n algorithm.
