The PMIC - AC/DC converters, offline switcher, and other power technologies are used to maintain system reliability, while multiplying the output of power sources. FSGM0465RWDTU is one of the newest products to join these technologies. This article will cover the application field and the working principle of FSGM0465RWDTU.

FSGM0465RWDTU is a monolithic current-mode AC/DC Fly-Buck converter from Fairchild Semiconductor. It integrates advanced high-voltage and low-voltage MOSFETs with a current and temperature-sensing circuit, along with a regulator and driver for constant on-time control. This design supports up to 65V input voltage, and delivers 3A continuous current at output voltages up to 60V with best-in-class efficiency of 93%. Its protection features include short-circuit protection and over-temperature protection.

The FSGM0465RWDTU is mainly used in high-wattage applications with multiple outputs voltage, such as LED lighting, telecom, server and data center, industrial, and automotive power devices. The low quiescent current, high-efficiency, wide input and output voltage range, and multiple protection features make this device a suitable solution for such demanding applications. Additionally, due to its low height, multiple modules can be easily stacked for use in space-saving applications.

The power switch is controlled by the FSGM0465RWDTU\'s current-mode PWM control with constant on-time as the regulation method, such that the output voltage will remain relatively constant as the input voltage and load current varies. The on-time of the switch is a function of the current-sense voltage and the feedback voltage. In normal operation, the voltage on the CS pin is sampled and then compared to the voltage on the FB pin, and the difference between them is amplified. If the CS voltage is larger than the FB voltage, the amplifier output causes an increase in the turn-on time of the MOSFET switch. If the CS voltage is smaller than the FB voltage, the amplifier output reduces the turn-on time. This process of comparing the two voltages and adjusting the turn-on time of the switch is repeated in each switching cycle.

Overall, the FSGM0465RWDTU is an ideal choice for high-wattage applications with multiple outputs, thanks to its wide input and output voltage range, low quiescent current, high efficiency and multiple protection features. Its current-mode PWM control with constant on-time regulation method also provides a reliable and consistent output voltage.
