BP85226DF
Overview
- Integrated VCC capacitor, freewheeling diode and power supply switcher IC with low standby consumption. feedback diode The BP85226DF can be configured as buck, buck-boost topologies for universal 85~265V AC inputs. The BP85226DF integrates a 650V 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 BP85226DF 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 BP85226DF features comprehensive protections, fid including short circuit protection (SCP), output over voltage protection (OVP), over load protection (OLP), FB open loop protection, cycle-by-cycle current limit, and over temperature protection (OTP). Con The BP85226DF is available for SOP-7 package.
