High Performance,
Integrated Current Mode
PWM Controllers
The CS5124 is a fixed frequency current mode controller designed
specifically for DCDC converters found in the telecommunications
industry. The CS5124 integrates many commonly required current
mode power supply features and allows the power supply designer to
realize substantial cost and board space savings.
The CS5124 integrates the following features: Internal Oscillator,
Slope Compensation, Sleep On/Off, Undervoltage Lock Out, Thermal
Shutdown, SoftStart Timer, Low Voltage Current Sense for Resistive
Sensing, Second Current Threshold for PulsebyPulse overcurrent
Protection, a Direct Optocoupler Interface and Leading Edge Current
Blanking.
The CS5124 has supply range of 7.7 V to 20 V and is available in 8
pin SOIC narrow package.
