FEATURES
BP85256D Ultra-high Integration Off-line Switcher IC The BP85256D is a high performance, highly● Integrated VCC capacitor, freewheeling diode and integrated power supply switcher IC with low standby feedback diode consumption. The BP85256D can be configured as
● Integrated 650V power MOSFET buck, buck-boost topologies for universal 85~265V AC
● Integrated high-voltage current source for self- inputs. External VCC capacitor and loop compensation components can be tia eliminated, which reduces cost and size of overall power systems, and improves reliability. The BP85256D employs multi-mode control algorithm. As a result, the no-load power consumption and the n average efficiency have been improved, and the audible noise is reduced. e The BP85256D features comprehensive protections, including short circuit protection (SCP), output over fid voltage protection (OVP), over load protection (OLP), FB open loop protection, cycle-by-cycle current limit, and over temperature protection (OTP).
