DC DC Switching Regulators: MAX5089ATE+T Application Field and Working Principle

The MAX5089ATE+T is a high-efficiency, step-down DC to DC-switching regulator from Maxim Integrated. It is designed for battery-powered applications that are sensitive to ripple and noise. The device operates with input voltage ranging from 4.5 V to 16.5 V and has a typical efficiency of 96%.The MAX5089ATE+T operates with a fixed output voltage of 2.5 V and offers a programmable switching frequency range of 400 kHz to 800 kHz. The step-down DC to DC switcher can provide up to 2 A of output current and offers a high-side and low-side driver current limit protection up to 10 A. It also features a built-in Under-Voltage Lockout (UVLO) protection which disables the device when the input voltage falls below 4.5 V.The working principle of the MAX5089ATE+T is based on a two-phase interleaved Architecture. It is composed of two main parts: the main switching module and the control circuit. When the power supply is applied, the main switching module starts to pull current from the input source and send it to the load. The control circuit regulates the switching frequency and feedback signal, specially designed for accurate and stable output voltage regulation.In order to achieve high efficiency, the switching module uses power MOSFETs in a Half-Bridge topology. The two power MOSFETs switch alternately in order to reduce switching losses. The built-in chip also features Switching Frequency Adjustment (SFA) which allows the user to select the operating switching frequency of the device.The MAX5089ATE+T also includes a Current Mode Control (CMC) circuit which provides a constant slope current during the switch-on and switch-off time of the power MOSFETs. This allows the device to have low output voltage ripple and noise, making it ideal for application that are sensitive to ripple and noise.The MAX5089ATE+T is a step-down DC to DC-switching regulator that offers a high efficiency, low output voltage ripple and noise, and a wide input voltage range of 4.5 V to 16.5 V. It is specifically designed for battery-powered devices like smart phones, tablets, and industrial handhelds. Thanks to its built-in under-voltage lockout (UVLO) protection, current limit protection, and Switching Frequency Adjustment (SFA), the MAX5089ATE+T is a reliable and versatile DC to DC-switching regulator that provides excellent performance.
