The • Wide Duty Cycle Range for Wide-Input Voltage controllers can also be implemented for stage or Dimming Range conversion where the power factor (PF) exceeds • Convenient 5-V Reference Output regulatory requirements for lighting. These controllers also have an accessible 5-V reference that could be • Undervoltage Lockout for Safe Operation used to power a microcontroller or other low power • Operation to 1-MHz peripheral components. The controllers operate in • 0.4-A Source/0.8-A Sink FET Driver fixed frequency current mode switching with minimal external parts count. Internally implemented circuits • Low 100-µA Startup Current include undervoltage lockout featuring startup current less than 100 µA, logic to ensure latched operation, a APPLICATIONS PWM comparator, and a totem pole output stage to • Residential LED Lighting Drivers for A19 sink or source peak current. The output stage, E12/E26/27, GU10, MR16, PAR30/38 Integral suitable for driving N-Channel MOSFETs, is low in Lamps the off state. Oscillator frequency and maximum duty • Drivers for Wall Sconces, Pathway Lighting cycle are programmed with two resistors and a and Overhead Lighting capacitor. • Drivers for Wall Washing, Architectural and The TPS92001/2 family also features full cycle soft Display Lighting start. The family offers UVLO thresholds and hysteresis levels for off-line and DC-to-DC systems. DEVICE TURN-ON TURN-OFF The TPS92001/2 is offered in the 8-pin MSOP (DGK) NUMBER THRESHOLD (V) THRESHOLD (V) and 8-pin SOIC (D) packages. The small MSOP TPS92001 10 package makes the device ideally suited for 8 TPS92002 15 applications where board space and height are at a premium 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
