UC2845N, Current-Mode PWM Controller, PDIP8, Texas Instruments
IC, UC2845N, Texas Instruments
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
