The UC3842B, UC3843B series are high performance fixed
frequency current mode controllers. They are specifically designed for
Off?Line and DC?DC converter applications offering the designer
a cost?effective solution with minimal external components. These
integrated circuits feature a trimmed oscillator for precise duty cycle
control, a temperature compensated reference, high gain error
amplifier, current sensing comparator, and a high current totem pole
output ideally suited for driving a power MOSFET.
Also included are protective features consisting of input and
reference undervoltage lockouts each with hysteresis, cycle?by?cycle
current limiting, programmable output deadtime, and a latch for single
pulse metering.
These devices are available in an 8?pin dual?in?line and surface
mount (SOIC?8) plastic package as well as the 14?pin plastic surface
mount (SOIC?14). The SOIC?14 package has separate power and
ground pins for the totem pole output stage.
The UCX842B has UVLO thresholds of 16 V (on) and 10 V (off),
ideally suited for off?line converters. The UCX843B is tailored for
lower voltage applications having UVLO thresholds of 8.5 V (on) and 7.6 V (off).
