BP8522D
Overview
- 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. As a result, the no-load power consumption and the average efficiency have been improved, and the e audible noise is reduced. The BP8522D features comprehensive protections, over fid load protection (OLP), FB open loop protection, cycle-by- cycle current limit, and over temperature protection (OTP).
