CS2844 Datasheet Current Mode Pwm Controller

Manufacturer: Cherry Semiconductor Corporation

Overview: CS2844/3845 SERIES CS2844/CS3844 CS2845/CS3845 Current Mode PWM Control Circuit with 50% Max Duty.

General Description

The CS3844/45 provides all the necessary

Key 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 1.
