PM1-03B-15-G

AC DC Converters

An AC DC Converter is a device used to convert alternating electric current (AC) into direct current (DC). Generally, AC DC converters are used in applications where the output voltage or current must be controlled precisely, such as in computing and photographic applications. The PM1-03B-15-G is an example of a versatile AC DC converter designed for a range of uses.

Application Field

The PM1-03B-15-G is a multichip module designed for full-bridge and other DC-DC converter applications. It is widely used for point of load converters, dc to dc converters, and audio power amplifiers. It is also ideal for Uninterruptable Power Supplies (UPS), Computer Auxiliary Equipment (CAE) Uninterruptable Power Supplies (UPS), and automobile motor control applications. With a wide input voltage range of 9-60V, it is capable of pushing up to a 15A maximum current output with a high efficiency rating of up to 97%.

Working Principle

The PM1-03B-15-G is a synchronous-rectified, full-bridge, low-noise, AC to DC converter. It works by using a control IC to control the switches. The control IC synchronizes both the high and low side switches to operate in an alternating fashion. In addition, the PM1-03B-15-G utilizes a ripple-tone feedback algorithm for optimal switching, which helps to reduce noise and reduce switching losses. The output voltage is stabilized by a voltage reference circuit, which helps to ensure a regulated DC voltage.

The PM1-03B-15-G also features a Low Voltage Lock Out (L/VLO) function which shuts the power off if the input voltage drops below the voltage setting. This helps to protect against voltage fluctuations and decreases the risk of damage to the device. Additionally, the PM1-03B-15-G features an output short-circuit protection circuit which will also shut the power off if a short circuit occurs.

Conclusion

The PM1-03B-15-G is a versatile AC to DC converter designed for a range of uses. It is widely used for point of load converters, dc to dc converters, audio power amplifiers, and computer auxiliary equipment. With a wide input voltage range of 9-60V, it is capable of pushing up to a 15A maximum current output and features a high efficiency rating of up to 97%. It utilizes a ripple-tone feedback algorithm for optimal switching, a voltage reference circuit for output voltage stabilization, and a number of built-in protections such as Low Voltage Lock Out and output short circuit protection.
