The MAX5094CASA+T is a pulse-width-modulation (PWM) current mode switching controller from Maxim Integrated. It is designed for DC-to-DC supplies and is part of their extensive voltage regulator product line. The device has been designed to achieve very low output voltage noise with accurate current and voltage regulation. It also reduces power consumption by enabling small output voltage range by clamping the output current.

Applications of the MAX5094CASA+T include telecom base station and remote radio heads, servers, storage, test and measurement equipment, plus automotive, industrial and consumer applications.

The MAX5094CASA+T supports a variety of power supply topologies, including buck, boost and SEPIC. It supports input voltages up to 85V, output voltages of up to 5V, and has also integrated a voltage reference, which allows for a single input/output solution.

The working principle of the MAX5094CASA+T lies in its current mode switching topology. It uses peak current mode control to keep its output voltage constant. The integrated voltage reference and voltage error amplifier compare the output voltage to an internally-set reference. The error amplifier output {which is then amplified) tells the high side driver to increase or decrease its switching frequency, which in turn modifies the output voltage.

The MAX5094CASA+T also incorporates a variety of protection features. This includes undervoltage lock-out circuitry, cycle-by-cycle current limiting, thermal shutdown and overtemperature protection.

To sum up, the MAX5094CASA+T is a versatile PWM switching controller which offers low-noise and low-power-consumption DC-DC solutions. It allows for a wide range of voltages at the input and output, and can support several power supply topologies. It also offers protection features, ensuring that the output supply is safe and consistent.
