A8483EEK-T is a DC-DC switching regulator with load power up to 10 W that is designed for use in many applications. It is a cost-effective, compact and energy-efficient solution for efficiency-critical applications like power supplies and battery chargers. The device takes a wide input voltage range of ±7V (2.5V to 75V) and provides 4.5V to 42V output voltage range. It also has a fast transient response with a maximum of 35 μs. It has a high efficiency of up to 92%.

The A8483EEK-T is configured by an external control circuit for regulating an output-voltage up to the commanded level. It does this by controlling the duty cycle of the output pulse width modulation (PWM) signal. It can be used as a voltage regulator or step-up/step-down transformer. It can also be used as a synchronous rectifier, a linear regulator or a constant current source. The A8483EEK-T is designed to handle a large load current with accuracy of up to 0.1%.

An internal synchronous rectifier makes A8483EEK-T highly efficient. It uses synchronous rectification to increase efficiency with high switching frequency. The current-mode control scheme helps to compensate in the output voltage for varying load current. This makes A8483EEK-T suitable for many power management applications.

The A8483EEK-T also contains many protection features like under-voltage lockout, output over-voltage protection, over-temperature protection, output short-circuit protection, and current limit. These protection features help ensure that the device operates reliably even under harsh conditions. The device is RoHS compliant.

The A8483EEK-T offers a comprehensive suite of features, making it an ideal power management solution for cost-sensitive applications. It is designed to provide high efficiency, fast transient response and excellent load regulation accuracy. It comes in the industry standard QFN-30 package and is compatible with surface mount assembly, reducing cost and improving reliability. Overall, the A8483EEK-T is a cost-effective and energy-efficient DC-DC switching regulator.
