SP6136ER1-L/TR Application Field and Working Principle

The SP6136ER1-L/TR is a type of DC to DC switching power supply controllers. It is applied for power systems requiring high power density such as automotive, consumer electronics and industrial systems. This device uses proprietary DC/DC switching technologies and implements a multiphase buck converter topology to deliver high power densities, efficiency and improved solutions.

Features

• High voltage integrated MOSFETs, up to 40 V
• 1.5 A to 6 A peak switch current capability
• 600 kHz to 2.1 MHz switching frequency
• Integrated linear regulator, up to 8 V
• Current limit, over-voltage, over-temperature, under-voltage protection
• 2-wire interface with SPI compatible
• Small package size: package-H: 8 mm x 18 mm

Working Principle

The SP6136ER1-L/TR is a multiphase buck switching controller. It operates with a constant frequency PWM scheme. The external switches are driven by the output of an oscillator which is controlled by the internal or external clock sources. The oscillator frequency is adjusted depending on the desired output voltage magnitude. The convergence of the output voltage to the programmed voltage is accomplished by a high-performance regulation loop. The output voltage is sensed through a DAC reference or an external feedback resistor divider network. The device can be used in an either single-phase or a multi-phase configuration.

Conclusion

The SP6136ER1-L/TR is a type of DC to DC switching power supply controllers which offer high power density, efficiency and improved solutions for power systems requiring high power density such as automotive, consumer electronics and industrial systems. It operates with a constant frequency PWM scheme and has an integrated linear regulator, up to 8 V. It has current limit, over-voltage, over-temperature, under-voltage protection and a 2-wire interface with SPI compatible. Thus, it is an ideal solution for DC to DC power supply applications.
