The A8498SLJTR-T is a DC-DC switching voltage regulator controller from the PMIC – Voltage Regulators family, specifically developed for offline, isolated, non-isolated and resonant applications. It is an advanced, high performance controller with a 1.2MHz switching frequency, that can deliver an output of 1A up to 60V with an 80% yield efficiency when used with an external power MOSFET. It has a wide voltage range of between 4.5V and 220V DC, with a wide operational and storage temperature range of -40°C to +125°C.

The A8498SLJTR-T works by controlling the voltage of a DC-DC converter. The DC-DC converter is connected to the main source, the output of which is rectified and converted into a constant voltage. The voltage regulator adjusts the voltage of the output to the required value. The voltage regulator utilizes PWM control and has a feedback loop for a steady output.

The A8498SLJTR-T features a wide range of features that make it an ideal choice for application in high power circuit designs. It has a maximum operating current of 1.2A and maximum voltage of 60V. It is equipped with a synchronous rectifier (SR) and integrated bootstrap diode. It has a wide programmable switching frequency of up to 1.2MHz, and soft start and frequency jittering options. The device is compatible with a variety of common protection and power-saving techniques, like short circuit, over-voltage and over-temperature protection. It also features wide dimming range, high speed transient response and very low output ripple. Besides, its pin-out is very versatile; it comes in three packages types: SOP-8, HVQFN-24 and HVQFN-20.

The A8498SLJTR-T is well suited for a variety of applications. It is bedges for LED drivers, DC-DC converters for UPS, auxiliary power supplies, computer servers and VRM, wireless communications and power supply controllers. It is also suitable for automotive, consumer and industrial applications, due to its wide voltage range, low power consumption and good protection features.

In conclusion, the A8498SLJTR-T is a state-of-the-art DC-DC switching voltage regulator controller from the PMIC – Voltage Regulators family. It offers a very wide voltage input range, high operating and storage temperature range, wide programmable switching frequency and other advanced features, making it an ideal choice for a variety of applications.
