A8650KEJTR-T application field and working principlePMIC (Power Management IC) technology can be used to regulate the power in a variety of applications, ranging from consumer electronics to industrial-grade system. DC-DC Switching Regulators are a popular type of PMICs that convert a DC input to another DC output with different voltage level. The A8650KEJTR-T is one such DC-DC Switching Regulator that offers high efficiency, a wide range of operating voltages, low output noise, and fast transient response characteristics.The A8650KEJTR-T is an integrated PMIC solution composed mainly of a synchronous rectified buck DC-DC converter, an on-chip high-side MOSFET, two low-side MOSFETs, and an adjustable linear regulator. It has an adjustable output voltage range from 0.85V to 3.3V and output current up to 3A.The A8650KEJTR-T features a synchronous rectified buck topology, which helps to achieve high conversion efficiency by allowing the use of low- resistance external MOSFET switches. Low-side MOSFETs are used to drive the LM5030-Q1 DBD high-side MOSFET, which is capable of switching frequencies up to 2.4 MHz. The A8650KEJTR-T also incorporates an adjustable regulator to ensure the accuracy of the output voltage.The A8650KEJTR-T has a wide range of applications. It is suitable for use in laptops, tablets, industrial systems, automotive, CNC machine tool, and many other electronic products. In power sensitive applications, its low quiescent current of 6 μA makes it ideal for applications such as green battery chargers or high-efficiency power supplies.The A8650KEJTR-T has a built-in pulse-by-pulse over-current protection feature which increases system safety. It is also equipped with a power-good indicator that allows users to monitor the output voltage levels. The A8650KEJTR-T has a power density of up to 7.7W/ cm2 and a maximum junction temperature of 105°C.To ensure best results, the A8650KEJTR-T should be used with an external 400V, 0.6mH inductor for the best performance. A high-quality input capacitor should also be used and at least a 3.3μF capacitor should be included on each voltage rail and the output in order to stabilize the circuit.In summary, the A8650KEJTR-T is a high-performance, high-efficiency adjustable DC-DC switching regulator. Its wide range of applications, low quiescent current, and high power density make it an ideal choice for a variety of electronic products. By combining an adjustable linear regulator with a synchronous rectified buck topology, the A8650KEJTR-T provides users with a reliable and cost-efficient power solution.
