Description

ON Semiconductor High Performance
Current Mode Controllers

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 here in an 8−pin dual−in−line package

 As many of our lines come in to us as surplus – sometimes from high end ‘Milspec’ type manufacturers we try to pass on our savings to our customers – often selling industrial grade or military spec components rather than the commercial equivalent.
