Sketch
The BP87112 is a current mode PWM switcher lC withhigh performance, high integration and low standbyconsumption. The BP87112integrates a650VMoS-bipolarcomposite power switch and a high-voltage currentsource which eliminates the startup resistors. ltsupports CCM and DCM operations. At full load, the lCoperates in 65 kHz fixed frequency. When the load goesdown,
Advantage
