The MAX5038AEAI25-T is a voltage regulator belonging to the PMIC - Voltage Regulators - DC DC Switching Controllers subcategory. It is a low-voltage, low-power controller capable of regulating a wide range of input voltages and delivering precise regulated output voltages. The MAX5038AEAI25-T can drive up to 2A at up to 1V. It is designed for battery-powered applications, such as mobile phones, tablets, and medical equipment. This device features low ripple, thermal protection, converter and load fault detection, as well as switching frequency synchronization and frequency foldback.

The MAX5038AEAI25-T is a single-stage switch mode device built on a standard dual N-channel power MOSFET topology. This device works in a pulse width modulation (PWM) scheme, operating in either continuous or discontinuous conduction mode. The MAX5038AEAI25-T employs an internal PLL-based ramp generator, which generates a stable reference signal for the PWM comparator. This ensures accurate timing for the MOSFET switching operation. During switching, the integrated driver of the MAX5038AEAI25-T controls the MOSFET gates. This helps to reduce EMI.

The MAX5038AEAI25-T offers various protections for the system and load. It has over-voltage protection, under-voltage protection, over-temperature protection, short-circuit protection, output overvoltage protection and current limit protection. It also provides a fault signal that can be used to indicate an output fault condition to the system. This allows the system to take instant corrective action.

The MAX5038AEAI25-T supports both pulse width modulation (PWM) and pulse frequency modulation (PFM) mode to make it suitable for a wide range of operational conditions. In PFM mode it is capable of providing high efficiency over a wide load range, while in PWM mode it ensures good load regulation and fast transient response. The frequency foldback technique of the MAX5038AEAI25-T prevents unnecessary power dissipation due to over current situations.

The MAX5038AEAI25-T is an excellent choice for applications where a precise regulated output voltage is required. It offers a wide range of protections, high efficiency, and a low power dissipation. This makes it well suited for battery powered applications that require an ultra-low standby power consumption.
