MAX8531EBTGGJ+T

The MAX8531EBTGGJ+T is a high-performance, low-cost voltage regulator for linear power applications. It provides adjustable current limiting, over-5V tolerance, and active-voltage-scaling features. Its wide input voltage range (from 10 V to 50 V) and adjustable output voltage range allow it to cover a wide range of applications. In addition, the device has thermal protection to prevent overheating, active current limiting to provide extra protection, and overtemperature monitoring for thermal shutdown.

The MAX8531EBTGGJ+T is designed for a variety of power-management applications. It is ideal for personal digital assistants (PDAs), laptops, personal digital video recorders (PDVRs), cell phones, and set-top boxes. It is also useful in powering servers, switches, routers, and other network equipment.

The MAX8531EBTGGJ+T voltage regulator operates with an input voltage range of 10 V to 50 V and an adjustable output voltage range of 0.8 V to 5 V. Active-voltage scaling allows it to provide higher VOUT by increasing the gate voltage. This provides better control over the output voltage, as well as improved power efficiency.

The MAX8531EBTGGJ+T includes two active current-limiting features, Soft-Start and Active Peak Current Protection (APCP). Soft-Start limits the instantaneous in-rush current during startup, maximizing reliability and increasing system stability. APCP limits the output current during the load-transient and overload conditions, preventing damage to the regulator circuit. It also provides dynamic load regulation, allowing the output voltage to remain constant even when the input and load currents change.

The MAX8531EBTGGJ+T voltage regulator works together with the MAX14781EKG+T dual operational amplifier in parallel-mode configurations. The amplifier can be used to increase the current output of the voltage regulator and enhance its stability, providing superior performance when driving heavy loads. The MAX14781EKG+T also provides thermal protection and output transistor clamping protection. The amplifier supports up to 1.3 A of output current with a single-ended, symmetric output of up to 6.5 V.

The MAX8531EBTGGJ+T is a cost-effective solution for high-performance, high-voltage linear power applications. It provides a current-limiting, over-5V tolerant, active-voltage-scaling, and thermal protection features. It is designed for use in PDAs, laptops, PDVRs, cell phones, and set-top boxes, as well as in network-infrastructure equipment such as servers, switches, and routers. The device works together with the MAX14781EKG+T dual operational amplifier to provide enhanced performance and stability when driving heavy loads.
