CS5124: Integrated Current Mode PWM Controller for Forward or Flyback (36 - 75 V Telecom Supply)

The CS5124 is an Integrated Current Mode PWM Controller designed specifically for dc-dc converters found in the 48V telecommunications industry. This PWM Controller integrates many commonly required current mode power supply features and allows the power supply designer to realize substantial cost and board space savings. CS5124: 400kHz w/VBIAS Pin, 195mV first current sense threshold The CS5124 integrates the following features: Internal Oscillator, Slope Compensation, Sleep On/Off, Under Voltage Lock Out, Thermal Shutdown, Soft Start Timer, Low Voltage Current Sense for Resistive Sensing, Second Current Threshold for Pulse by Pulse Over Current Protection, a Direct Optocoupler Interface and Leading Edge Current Blanking. The CS5124 Integrated Current Mode PWM Controller has supply range of 7.7V to 20V and can be powered from a 36-75.0 volt telecom supply.
