TL2842BP datasheet



The TL2842BP, TL284xB and TL384xB series of control integrated circuits provide the features that are necessary to implement off-line or dc-to-dc fixed-frequency current-mode control schemes, with a minimum number of external components. Internally implemented circuits include an undervoltage lockout (UVLO) and a precision reference that is trimmed for accuracy at the error amplifier input. Other internal circuits include logic to ensure latched operation, a pulse-width modulation (PWM) comparator that 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 when it is in the off state.


• Low Start-Up Current (<0.5 mA)

• Automatic Feed-Forward Compensation

• Latching PWM for Cycle-by-Cycle Current Limiting

• Internally Trimmed Reference With Undervoltage Lockout

• High-Current Totem-Pole Output Undervoltage Lockout With Hysteresis

• Double-Pulse Suppression
