ST 3845B High Performance Current Mode PWM Controller Ceramic Diode Extensive absorbing transient energy capabilitySTMicroelectronics 3845B is a high Performance current mode PWM controller. The 3845B control IC family provides the features required to implement off line or DC to DC fixed frequency current mode control schemes with a low external part count. Internally implemented circuits include a trimmed oscillator with start up current less than 0. 5mA for precise DUTY CYCLE CONTROL under voltage lock out, a precision reference trimmed for accuracy at the
