DC2380A-B

The DC2380A-B is an evaluation board developed for DC/DC converters (off-line SMPS) applications. The board utilizes an integrated ultra-miniature switch mode power supply (SMPS) IC with constant frequency, current mode PWM control. The primary side of the DC2380A-B is optimized for universal AC input from 85V to 265VAC. The secondary side provides both adjustable (C2380A) or fixed (C2380B) voltage outputs of up to 24V. The board is suitable for a variety of DC/DC converter applications including low and mid-power industrial equipment, consumer electronics, laptops and telecommunications systems.

The DC2380A-B enables users to evaluate the performance of their DC/DC off-line converter designs in applications requiring a wide input range (85V to 265VAC), high efficiency and simple regulation. It also allows designers to test a range of control and protection features suitable for high voltage applications such as short circuit protection, over voltage protection, overload protection and thermal shutdown.

The DC2380A-B achieves high efficiency levels in part due to its integrated ultra-miniature switch mode power supply (SMPS) IC with PWM control. The IC is designed with an adjustable oscillation frequency (250 kHz to 650 kHz adjustable) and a high peak current capability of up to 2.2A at a 12V output voltage, allowing it to deliver higher output power than many competing designs. The DC2380A-B also supports a fully regulated output over a wide operating temperature range (up to 85°C).

In terms of operating performance, the DC2380A-B features an adjustable output voltage range from 4.0V to 24V. Output ripple and noise are kept at a low level of 20mV peak-to-peak and 1.5mV RMS, respectively. The device is also equipped with protections such as short circuit protection, over voltage protection and thermal shutdown, providing a high degree of confidence against common operation faults.

The DC2380A-B is an ideal solution for a variety of applications including low and mid-power industrial equipment, consumer electronics, laptops, and telecommunications systems. This flexibility makes it suitable for a wide range of industries and applications. Target applications include LED lighting, domestic appliances, power tools, medical equipment, and automotive components.

In conclusion, the DC2380A-B is an ideal choice for DC/DC off-line converter applications requiring a wide input voltage range, high efficiency and simple regulation. With its adjustable output voltage range, low output ripple and noise, and protection features, it provides a rugged, reliable and cost-effective solution for a variety of applications.
