The CS5124/6 is a fixed frequency current mode controller
designed specifically for DC−DC converters found in the
telecommunications industry. The CS5124/6 integrates many
commonly required current mode power supply features and allows
the power supply designer to realize substantial cost and board space
savings. The product matrix is as follows:
CS5124: 400 kHz w/VBIAS Pin, 195 mV first current sense threshold.
CS5126: 200 kHz w/SYNC Pin, 335 mV first current sense threshold.
The CS5124/6 integrates the following features: Internal Oscillator,
Slope Compensation, Sleep On/Off, Undervoltage Lock Out, Thermal
Shutdown, Soft−Start Timer, Low Voltage Current Sense for Resistive
Sensing, Second Current Threshold for Pulse−by−Pulse overcurrent
Protection, a Direct Optocoupler Interface and Leading Edge Current
Blanking.
The CS5124/6 has supply range of 7.7 V to 20 V and is available in
8 pin SOIC narrow package.
Features Pb−Free Package is Available Line UVLO Monitoring Low Current Sense V oltage for Resistive Current Sensing External Synchronization to Higher or Lower Frequency Oscillator
