TL2845P datasheet

 

Description :

The TL2845P, TL284x and TL384x series of control integrated circuits provide the features that are necessary toimplement 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.

Features :

1. Optimized for Off-Line and dc-to-dc Converters

2. Low Start-Up Current (<1 mA)

3. Automatic Feed-Forward Compensation

4. Pulse-by-Pulse Current Limiting

5. Enhanced Load-Response Characteristics

6. Undervoltage Lockout With Hysteresis

7. Double-Pulse Suppression

8. High-Current Totem-Pole Output

9. Internally Trimmed Bandgap Reference

10. 500-kHz Operation

11. Error Amplifier With Low Output Resistance

12. Designed to Be Interchangeable With UC2842 and UC3842 Series
