Product Description

The TL284x and TL384x 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. Some of the internally implemented circuits are an undervoltage lockout (UVLO), featuring a start-up current of less than 1 mA, and a precision reference 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.
Optimized for Off-Line and DC-to-DC Converters
Low Start-Up Current (< 1 mA)
Automatic Feed-forward compensation
Pulse-by-Pulse Current Limiting
Enhanced Load-Response Characteristics
Undervoltage Lockout With Hysteresis
Double-Pulse Suppression
High-Current Totem-Pole Output
Internally Trimmed Bandgap Reference
500-kHz Operation
Error Amplifier With Low Output Resistance
Designed to be Interchangeable with UC2842 and
UC3842 Series
