The BP870X family is a series of highly integratedcurrent mode PWM switcher ICs with highperformance, low standby consumption suitable fordesigning flyback converters up to 25 W.
The BP870X integrates a 650 V power MOSFET and ahigh-voltage current source which eliminates thestartup resistors.lt supports CCM and DCM operations.
