Current Mode PWM
Control Circuit with
50% Max Duty Cycle
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 16 V and turn off at
10 V. In the CS2845/CS3845 turn on is at 8.4 V and turn off at 7.6 V.
Other features include low start–up current, pulse–by–pulse current
limiting, and a high–current totem pole output for driving capacitive
loads, such as gate of a power MOSFET. The output is low in the off
state, consistent with N–channel devices.
