TS3842B/3843B  
High Performance Current Mode Controller  
Designed for Off-Line and DC-to-DC  
converter applications.  
DIP-8  
SOP-8  
General Description  
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.
