Overview
The UC3844B, UC3845B, UC2844B, and UC2845B are high-performance fixed-frequency current-mode controllers designed for off-line and dc-dc converter applications.
Key Features
These devices offer a cost-effective solution with minimal external components, featuring an oscillator, temperature-compensated reference, high-gain error amplifier, current sensing comparator, and high-current totem pole output stage.
They also include protective features such as input and reference undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and a latch for single-pulse metering.
Package Options
The devices are available in 8-pin dual-in-line and surface mount (SOIC-8) packages, as well as a 14-pin plastic surface mount (SOIC-14) package with separate power and ground pins for the totem pole output stage.
