Switching or switching-mode DC-to-DC controllers have revolutionized power supply design. Today’s topologies are used in many applications in the industry, such as computer power supplies, telecommunications, automotive, and industrial electronics. Although the number of applications continues to grow steadily, they all have similar basic operating characteristics that define the way they function. MAX1634/MAX1635/MAX1636/MAX1637 are general-purpose, monolithic, high-voltage, synchronous dc-to-dc switching-mode controllers.

PMIC or Power Management IC or Voltage Regulators or Double Edge Triggered (DET) DC-DC Switching Controllers encompass a range of common tools which provide a wide range of options including linear and switcher regulator technologies. MAX1634AEAI+T is one of the most advanced DC-DC (Direct Current to Direct Current) switching controllers in market. This unit integrates many features like soft start, built in oscillator and active current limit features into the design

The MAX1634AEAI+T DC-DC Switching Controller offers immense benefits when compared to traditional linear regulator switching approaches. It features an improved efficiency, higher power handling capabilities, much more power density and better power factor correction. It also provides a much wider input voltage range while enabling voltage conversion over a wide range without any need of external components.

The MAX1634AEAI+T is a DC-DC switching controller which uses an on-chip buck converter to step the voltage down from a high to a low source. It uses a buck converter Topology, making it an ideal solution for applications such as voltage regulated power supplies which require a fixed output voltage and current. The MAX1634AEAI+T converter also offers high efficiency, fast transient response and a current mode control for dynamic response. Moreover, the device includes thermal shutdown for over-temperature protection, as well as short-circuit protection.

The MAX1634AEAI+T switching controller typically works with an external power MOSFET and rectifier diode to turn power into fixed adjustable output voltage and current. The MAX1634AEAI+T uses Pulse Width Modulation (PWM) to control the MOSFET switch, which produces a steady output voltage, no matter the input voltage. This voltage is determined by the internal resistors. The controller contains a circuit that operates in current mode, enabling it to detect the output current flowing in the MOSFET Mosfet switch. This current is then compared to the maximum current set-point. If the current is larger than the pre-defined set-point, the PWM signal is inverted and the switch is disabled. This means that the current-mode control reduces cycles in the converter and generates less energy losses.

The MAX1634AEAI+T DC-DC switching controller boasts a wide range of advantages over linear switching controllers. It is highly efficient, offers low amplitude noise and excellent stability, and allows for an adjustable output voltage and a wide input voltage range. It is also suitable for use in applications such as computer power supplies, telecommunications, automotive, and industrial electronics.
