Overview
CS5124 High Performance, Integrated Current Mode PWM Controllers The CS5124 is a fixed frequency current mode controller designed specifically for DC−DC 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, 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 has supply range of 7.
7 V to 20 V and is available in 8 pin SOIC narrow package.
Features • 400 kHz Oscillating Frequency • Line UVLO Monitoring • Low Current Sense Voltage for Resistive Current Sensing • Bias for Startup Circuitry • Thermal Shutdown • Sleep On/Off Pin • Soft−Start Timer • Leading Edge Blanking • Direct Optocoupler Interface • 90 ns Propagation Delay • 35 ns Driver Rise and Fall Times • Sleep Mode • Pb−Free Packages are Available http://onsemi.
