DC-DC switching controllers are an expansive branch of power management integrated circuits (PMICS). The Maxim Integrated MAX1761EEE+ is a multi-mode, non-synchronous buck-boost switching controller suited for a variety of applications from battery powered products to cellular handsets. It provides step-up, step-down, and inverting functionality, efficiencies up to 96%, and up to 5A output current.
The MAX1761EEE+ is composed of a control loop and power stage. The control loop is responsible for pulse-width modulation (PWM) and loop compensation while the power stage handles power conversion with its external components. The control loop architecture allows the user to select switching frequency based on output voltage ripple requirements.
The power stage structure of the MAX1761EEE+ consists of the main switch, sense resistor, and other external components including inductors, capacitors, diodes, and an Enable pin. When the main switch is enabled, the input voltage is converted to a voltage proportional to the duty cycle of the main switch. This solution fosters efficiency working with a single input voltage and a single output voltage.
The main application of the MAX1761EEE+ is power regulation. It is a high-efficiency method for supplying power that is available from multiple battery supply sources and is suitable for non-critical automotive power supplies or when the power factor correction (PFC)section is used. As the MAX1761EEE+ is non-synchronous, the switching frequency needs to be within the resonant range of the connected components for optimal electrical characteristic performance. This can be done by using a synchronous buck-boost controller like the MAX1766EEE+.
MAX1761EEE+ is a highly efficient buck-boost switching controller operating with a single input and single output. The power stage consists of the main switch, sense resistor, and other external components including capacitors, inductors, diodes, and an Enable pin. The MAX1761EEE+ features a control loop architecture allowing the user to adjust switching frequency easily and optimize the application performance and efficiency. It is ideal for battery powered products, cellular handsets, and non-critical automotive solutions. The MAX1761EEE+ achieves an up to 96% efficiency, up to 5A output current, and is a suitable choice for low-voltage buck-boost applications.
