DescriptionThe UC3845N is a Current Mode PWM Controller optimized for off-line and DC to DC converters. This device provides the necessary features to implement off-line or DC-to-DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include under-voltage lockout featuring start up current less than 1mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control and a totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N-channel MOSFETs, is low in the off state.Optimized for off-line and DC to DC convertersLow start up current (<1mA)Automatic feed forward compensationPulse-by-pulse current limitingEnhanced load response characteristicsUnder-voltage lockout with hysteresisDouble pulse suppressionHigh current totem pole outputInternally trimmed bandgap referenceGreen product and no Sb/BrApplicationsPower ManagementProduct InformationInput Voltage:25VOutput Voltage:13.5VOutput Current:1ASupply Voltage Min:12VSupply Voltage Max:25VController IC Case Style:DIPNo. of Pins:8PinsFrequency:450kHzOperating Temperature Min:0°COperating Temperature Max:70°CPackage includes: 1xUC3845
