UC3842BD1 General Description

The UC284xB family consists of various members with differences in under-voltage lockout thresholds and maximum duty cycle ranges. For instance, the UC2842B and UC2844B have UVLO thresholds of 16V (on) and 10V (off), making them ideal for off-line applications. On the other hand, the UC2843B and UC2845B have different UVLO thresholds of 8.5V and 7.9V. Depending on the specific model, duty cycles can approach 100% or range from zero to less than 50% by incorporating an internal toggle flip flop

Key Features

Accurate voltage regulation and control
Pulse-frequency modulation options
Voltage transient suppression and filtering
Low-voltage startup and shutdown
