Ordering Information
The TS3842B and TS3843B series are high performance fixed frequency current mode controllers.
This is specifically designed for Off-Line and DC-to-DC converter applications offering the designer a
cost effective solution with minimal external components. This 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.
This device is available in 8-pin dual-in-line plastic packages as well as the 8-pin plastic surface
mount (SOP-8). The SOP-8 package has separate power and ground pins for the totem pole output
stage.
The TS3842B has UVLO thresholds of 16V (on) and 10V (off), ideally suited for off-line converters.
