PMIC (Power Management Integrated Circuits) is a power management technology that is used to regulate power consumption in different types of circuits. The FSD210BM is an AC/DC converter, offline switcher, specifically developed by Fairchild Semiconductor to handle a wide range of off-line single-phase AC/DC conversion applications.

The FSD210BM offers an efficient, high-performance solution for cost-effective, space-saving power management solutions. It has a minimum power dissipation of 370mW, a wide range of input voltage adjustment from 4V to 50V, and a maximum allow 7.5A current. This power converter can detect input under-voltage lockout and based on its current limit function, it can detect and protect against output short circuits and other faulty conditions.

The FSD210BM also offers a low component count solution. It integrates all the required components in a single, cost-effective package. It eliminates the need for additional external components such as an opto-coupler, gate ice, bias resistor, inrush current limit and EMI filters, significantly reducing the assembly costs of the application.

The FSD210BM is based on a switched-mode design, using Pulse Width Modulation (PWM) or Pulse Frequency Modulation (PFM). When AC voltage feeds the rectifier bridge, the diode output will be filtered into DC voltage. This will then enter the controlled mode– in such mode, the controller will decide whether the output voltage is higher than the desired voltage, low current will be sent to the control pin to reduce duty cycle, while if the output voltage is lower than the desired voltage, more current will be sent to the control pin, thus increasing the duty cycle and achieving the desired voltage. The FSD210BM is an excellent power converter solution for many low-cost AC/DC conversion applications.

The Fairchild FSD210BM offers an efficient, cost-effective, and easy-to-use solution for a variety of off-line AC/DC conversion applications, thanks to its low component count, wide input voltage adjustment, and high power efficiency. This power management IC is ideal for cost-sensitive applications where space-saving and efficiency are of the highest priority.
