UC3842規(guī)格書(shū)詳情
Description
The 3842/43/44/45 are fixed frequency current mode PWM controller. They are specially designed for OFF?Line and DC to
DC converter applications with a minimal external components. Internally implemented circuits include 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 circuitry includes built undervoltage lockout and current
limiting. The 3842 and 3844 have UVLO thresholds of 16 V (on) and 10 V (off). The corresponding thresholds for the 3843/
45 are 8.4V (on) and 7.6V (off). The 3842) and 3843 can operate within 100 duty cycle. The 3844 and 3845 can operate within 50 duty
cycle.
The 384X has Start-Up Current 0.17mA (typ).
