FMSMMB130M5

The FMSMMB130M5 is a point-of-load (POL) DC-DC converter that offers power solution viable in both distributed and non-distributed power systems. These converters are specifically designed to supply intermediate bus voltage for point-of-load applications, thus enabling greater system design flexibility, reduced board space, improved current integrity, lower system cost, and improved system reliability. The FMSMMB130M5 offers the ultimate combination of size, efficiency, features, and low cost.

The FMSMMB130M5 incorporates a high-performance microcontroller-based PWM controller and provides an output adjustable from 0.8V to 13.2V. It also features built-in embedded components like a synchronous rectifier, a high-voltage, low-on-resistance switch, a power MOSFET, and a wide range of current limiting possibilities. This converter also features a wide input voltage range of 5V to 21V, making it ideal for applications requiring lower input voltages.

The FMSMMB130M5 has a multitude of useful features like active pre-biased output for load current sharing, an output voltage regulation of ±1%, adjustable current limit, a fast analog and serial controlled shutdown, and more. The converter is also EMI/EMC compliant and includes under-voltage lockout protection and thermal protection as well. Additionally, this converter is designed to operate without external components, and has a wide ambient temperature range of -40°C to 105°C.

The FMSMMB130M5 is suitable for a wide range of power management applications, including industrial, medical, communication, and consumer electronics, as well as light-emitting diode (LED) lighting. In addition to these applications, it is also used for automotive and portable power system designs due to its low weight and small size.

In terms of its working principle, the FMSMMB130M5 is based on a switched-mode power supply (SMPS), which uses pulse modulation technique to regulate the output voltage and current of the device. The SMPS’s operation is based on the principle of control and regulation, where the input voltages and currents are alternately switched on and off, and the average value of each is determined by varying the duty cycle. This generates a DC output voltage that is similar to the average input voltage. To regulate the output, the SMPS utilizes a feedback loop to compare the output and input voltages and adjusts the duty cycle accordingly to maintain the load voltage.
