The BP85226DF is a high performance, highly integrated power supply switcher IC with low standby consumption.
The BP85226DF can be configured as buck, buck-boost topologies for universal 85~265V AC inputs.
The BP85226DF integrates a 650V power MOSFET, a high- voltage current source for self-biasing, a current sensing circuit, an output feedback circuit, a freewheeling diode and an advanced controller. External VCC capacitor and 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 algorithm. As a result, the no-load power consumption and the average efficiency have been improved, and the audible noise is reduced.
The BP85226DF features comprehensive protections, 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).
The BP85226DF is available for SOP-7 package.
