Current Mode Pwm Controller

The Bay Linear B3842 B3843 B3844 B3845 are fixed frequency current- mode PWM Controller These devices are designed for Off- Line and DC-to-DC converter applications with minimum external components. The B3842 family Feature a trimmed Oscillator for precise duty cycle control, a temperature compensated reference, high gain error Amplifier current sensing Comparator and a high current totempole output. Ideally suited for driving a power N-Channel MOSFETs It is low when is on off stage. Protection circuitry includes built in under-voltage lockout and current limiting. Major differences between members of these series are the UVLO thresholds and maximum duty-cycle ranges. Typical UVLO thresholds of 16V (on) and 10V (off) on the B3842 and B3844 devices make them ideally suited to off-line applications. These corresponding typical thresholds for the B3842 and B3845 devcies are 8.4V (on) and 7.6V (off). The B3842 and B3843 devcies CAN operate to duty cycles approaching 100%. A duty-Cycle range of 0 to 50% is obtained by the B3844 and B3845 by the addition of an internal toggle Flip-Flop which blanks the output off every other Clock cycle. It id available in 8 pin DIP and SOIC packages. By Unkown
