Description
The 2842/43/44/45 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 2842 and 2844 have UVLO thresholds of 16V (on) and 10V (off). The corresponding thresholds for the
2843/ 45 are 8.4V (on) and 7.6V (off). The 2842 and 2843 can operate within 100 duty cycle.
The 2844 and 2845 can operate within 50 duty cycle.
The 284X has Start-Up Current 0.5mA (typ).
Features
Low Start-Up and Operating Current
High Current Totem Pole Output
Undervoltage Lockout With Hysteresis
Operating Frequency Up To 500KHz
