The TS3842B/3843B series are high performance fixed frequency current mode controllers.
The TS3842B and TS3843B series are high performance fixed frequency current mode controllers designed for off-line and DC-to-DC converter applications. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, a high gain error amplifier, and a high current totem pole output ideally suited for driving a power MOSFET.
