The TPS92001/2 family of general LED lighting PWM controllers containscontrol and drive circuitry required for off-line isolated or non-isolated LEDlighting applications.The controllers can support Phase Cut TRIAC dimming with minimal externalcomponents. The controllers can also be implemented for stage conversion wherethe power factor (PF) exceeds regulatory requirements for lighting. Thesecontrollers also have an accessible 5-V reference that could be used to power amicrocontroller or other low power peripheral components. The controllersoperate in fixed frequency current mode switching with minimal external partscount. Internally implemented circuits include undervoltage lockout featuringstartup current less than 100 μA, logic to ensure latched operation, a PWMcomparator, and a totem pole output stage to sink or source peak current. Theoutput stage, suitable for driving N-Channel MOSFETs, is low in the off state.Oscillator frequency and maximum duty cycle are programmed with two resistorsand a capacitor. The TPS92001/2 family also features full cycle soft start. The family offersUVLO thresholds and hysteresis levels for off-line and DC-to-DC systems. TheTPS92001/2 is offered in the 8-pin MSOP (DGK) and 8-pin SOIC (D) packages. Thesmall MSOP package makes the device ideally suited for applications where board
