UC3843B
Description
The UC384xB family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count.
Key Features
- to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count
- The output stage, suitable for driving N-Channel MOSFETs, is low in the offstate
- Differences between members of this family are the under-voltage lockout thresholds and maximum duty cycle ranges
- The UC3842B and UC3843B can operate to duty cycles approaching 100%
