CS2845 - Current Mode PWM Controller

Download the CS2845 datasheet PDF. This datasheet also covers the CS2844 variant, as both devices belong to the same current mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • The CS3844/45 provides all the necessary features to implement off-line fixed frequency current-mode control with a minimum number of external components. The CS3844 family incorporates a new precision temperature-controlled oscillator to minimize variations in frequency. An internal toggle flip-flop, which blanks the output every other clock cycle, limits the duty-cycle range to less than 50%. An undervoltage lockout ensures that VREF is stabilized before the output stage is enabled. In the C.

CS2844/3845 SERIES CS2844/CS3844 CS2845/CS3845 Current Mode PWM Control Circuit with 50% Max Duty Cycle Description Features The CS3844/45 provides all the necessary features to implement off-line fixed frequency current-mode control with a minimum number of external components. The CS3844 family incorporates a new precision temperature-controlled oscillator to minimize variations in frequency. An internal toggle flip-flop, which blanks the output every other clock cycle, limits the duty-cycle range to less than 50%. An undervoltage lockout ensures that VREF is stabilized before the output stage is enabled. In the CS2844/CS3844 turn on occurs at 16V and turn off at 10V. In the CS2845/CS3845 turn on is at 8.4V and turn off at 7.6V.
