The BP85226D is a high performance, highly integrated power supply switcher IC with low standby consumption.
The BP85226D can be configured as buck, buck-boost topologies for universal 85~265VAC inputs.
The BP85226D 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 BP85226D 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 BP85226D 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 BP85226D is available for SOP-7 package.
