Details
Offering a comprehensive set of features essential for current mode control schemes in off-line or DC to DC applications, the UC3842BN control IC stands out for its efficient design and minimal external parts requirements. Boasting a trimmed oscillator for precise duty cycle control, a precision reference for error amp input accuracy, and logic for latched operation, this IC ensures reliable performance. The integrated PWM comparator also features current limit control, while the totem pole output stage is capable of sourcing or sinking high peak currents with low off-state current. The UC2842B and UC2844B variants are tailored for off-line use, with under-voltage lockout thresholds set at 16V (on) and 10V (off). Conversely, the UC2843B and UC2845B models have thresholds of 8.5V and 7.9V, respectively. Additionally, the UC2842B and UC2843B allow for duty cycles approaching 100%, while the UC2844B and UC2845B achieve a range of zero to < 50% duty cycle via an internal toggle flip flop mechanism
