High Performance,
Integrated Current Mode
PWM Controllers
The CS5124/6 is a fixed frequency current mode controller
designed specifically for DCDC 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/V
BIAS
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, 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 CS5124/6 has supply range of 7.7 V to 20 V and is available in
8 pin SOIC narrow package.
