UC2845N
Fabricant : Texas Instruments
(22 avis)
Description :
The UC2845N provides 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. The internally implemented circuit includes 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.
Features
Pulse-by-pulse current limiting
Double-pulse suppression
Error amplifier with low output resistance
Up to 500-kHz operation
Applications
Switching regulators of any polarity
Transformer-coupled DC-DC converters
