1 / 12 page ©2000 Fairchild Semiconductor International www.fairchildsemi.com Rev. 5.0 Features • Low Start Up Current • Maximum Duty Clamp • UVLO With Hysteresis • Operating Frequency Up To 500KHz Description The KA3842B/KA3843B/KA3844B/KA3845B are fixed frequency current-mode PWM controller. They are spe- cially designed for Off - Line and DC-to-DC converter applications with minimum 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 totempole output Ideally suited for driving a power MOSFET. Protection circuity Includes built in under-voltage lockout and current limiting. The KA3842B and KA3844B have UVLO thresholds of 16V (on) and 10V (off) The KA3843B and KA3845B are 8.5V (on) and 7.9V (off) The KA3842B and KA3843B can operate within 100% duty cycle. The KA3844B and KA3845B can operate with 50% duty cycle. 8-DIP 14-SOP 1 1 KA3842B/KA3843B/KA3844B/KA3845B SMPS Controller |
