CS5124 General Description
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: 400kHz w/VBIAS Pin, 195mV first current sense threshold
CS5126: 200kHz w/SYNC Pin, 335mV first current sense threshold
The CS5124/6 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 CS5124/6 has supply range of 7.7V to 20V and is available in 8 pin SO narrow package.
