BP85256D
Overview
- 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. The BP85256D integrates a 650 V power MOSFET, a high-voltage current source for self-biasing, a current l sensing circuit, an output feedback circuit, a freewheeling diode and a controller. 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). Con The BP85256D is available in SOP-7 package. biasing
