MAX15001AEUB+T Datasheet/PDFMAX15001AEUB+T Application Field and Working Principle
The MAX15001AEUB+T is a dc-dc switching controller from the PMIC - Voltage Regulators - DC DC Switching Controllers family. It provides improved power efficiency and a wide range of choice for off-line, non-isolated high power density designs. The MAX15001AEUB+T is a monolithic, PWM (pulse-width-modulation) DC-DC switching controller that operates in the boundary conduction mode. As a single-channel controller, the MAX15001AEUB+T is capable of producing a fixed output voltage with high power efficiency while requiring a minimum number of external components. It provides highlight features such as integrated synchronous rectifier control and a built-in transconductance error amplifier.
Application Field
The MAX15001AEUB+T is ideally suited for power factor correction, AC/DC converters, DC/DC converters, and other switch mode power supply (SMPS) applications. It is especially suitable for applications that require high current and low ripple, such as computers, switching power supplies and other small electronic devices. Due to its simple design, the MAX15001AEUB+T is also well-suited for driving MOSFETs and IGBTs.
Working Principle
The MAX15001AEUB+T operates in boundary conduction mode, which means that it has a fixed operating frequency and duty cycle. The operating frequency of the MAX15001AEUB+T can be programmed by an external resistor, allowing the user to set the frequency at a value that is appropriate for the application. The duty cycle is controlled by the device’s internal transconductance error amplifier. When a signal is applied to the feedback input, an error signal is generated, and the error signal is used to control the duty cycle of the output signal. The duty cycle is adjusted in order to maintain the desired output voltage. The MAX15001AEUB+T also has an integrated synchronous rectifier control, which allows it to drive both low-side and high-side MOSFETs, as well as IGBTs. This provides improved efficiency compared to conventional non-synchronous rectifiers. The MAX15001AEUB+T also has a built-in frequency jitter function, which helps to improve the power supply\'s transient response and reduce EMI emissions.
Conclusion
The MAX15001AEUB+T is a high-efficiency, high-power DC-DC switching regulator from the PMIC - Voltage Regulators - DC DC Switching Controllers family. Its features, such as the built-in synchronous rectifier control and frequency jitter function, make it ideally suited for power factor correction and switch mode power supply applications. Its high power efficiency and built-in transconductance error amplifier make it a great choice for applications that require high current and low ripple.
