It is capable of operating in a wide range of applications, including high-performance DC/DC converters, low-power mobile computers, and industrial equipment. The ISL6729IU is a high-performance, single-chip hybrid switch mode PWM controller, offering high speed motor drive, adjustable Voltage positioning, and high efficiency power supply conversion.
Application Field
The ISL6729IU is designed for use in a wide range of different application fields. It is suitable for applications such as: DC-DC converters, high-performance battery pack chargers, automotive DC-DC converters, telecom public switch power supplies, military grade power supplies and portable appliance power regulation. It offers high efficiency, low noise operation and long operation life.
The ISL6729IU is particularly well suited for use in applications that require adjustable voltage positioning, such as lithium-ion battery pack charging and telecom power supply applications. It is also ideal for use in applications that require high-speed motor drive, such as automotive DC-DC converters. It provides full featured, low power, high efficiency power conversion in applications where space, power and cost are a concern.
Working Principle
The ISL6729IU is a PWM switch mode controller. It operates using a pulse-width modulation (PWM) technique, where the output voltage is filtered from an AC waveform. The PWM switching technique helps to reduce power dissipation while increasing efficiency. The controller also helps to regulate the output voltage and current by controlling the on and off time of the PWM switching waveform.
The ISL6729IU includes a Control Loop that works to keep the output voltage stable. The Control Loop maintains a regulated output voltage across a range of different load and input voltage conditions. The controller includes an internal band gap reference voltage to provide a stable voltage against temperature variations. The controller has a programmable slew rate and one P-Channel MOSFET switch.
Conclusion
The ISL6729IU is a single chip hybrid switch mode PWM controller from Intersil Corporation. It is ideal for applications requiring adjustable voltage positioning and high speed motor drive, such as battery pack charging and automotive DC-DC converters. It works using a pulse-width modulation technique and includes an internal band gap reference voltage to provide stable voltage under temperature variations. Its high efficiency, low noise operation and long operation life make it a great choice for many applications.
