The UC3845 fixed frequency current mode controller is made for off-line and DC-to-DC converter applications and provides a low-cost option with few external components for the designer. These coordinated circuits include a managed oscillator for exact obligation cycle control‚ a temperature repaid reference‚ high increase blunder speaker‚ current detecting comparator‚ and a high current chain of command yield unmistakably appropriate for driving a power MOSFET
