UC3844BVDG General Description

In addition to its core functionalities, the UC3844BVDG also incorporates protective features such as input and reference undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and a latch for single-pulse metering. Furthermore, a flip-flop mechanism is included to blank the output every other oscillator cycle, enabling the programming of output deadtimes ranging from 50% to 70%

Key Features

The UC3844BVDG is a high performance current mode controller designed for off-line power supplies

It features a precision voltage reference, programmable oscillator frequency, low startup and operating current, and adjustable soft-start

Additionally, it offers cycle-by-cycle current limiting, on-time control, and high output drive capability

It is available in an SOIC-14 package

Application

High efficiency power supply solution
Versatile application in various industries
Reliable performance in automotive systems
