Mornsun Switching Regulator Series Extended with Introduction of 2A Range.

Global power supply manufacturer Mornsun has increased the application range of its successful non-isolated Switching Regulator series with the introduction of the 2A rated K78xx-2000R3 product range. These new switching regulators feature an ultra-wide input range of 6-36VDC with outputs of 3.3, 5, 9, 12 and 15V DC.

Output features include a typical voltage accuracy of ±2%, line regulation of±0.4%, load regulation of±0.5% (10-100% load), continuous (self-recovering) short circuit protection and low ripple & noise (typically 30mV pk-pk, 20Mhz bandwidth).

Efficiency is up to 95% with 0.1mA ultra-low no load input current and no requirement for a heatsink. This reduces the installation time and provides additional space around the converter when compared to traditional linear regulators. The operating temperature range of these devices is -40°C to +85°C and they are housed in a UL94 V-0 rated package measuring 11.5 x 9 x 17.5mm.

In addition to the 2A range the latest R3 series of Switching Regulators also includes devices with 0.5A and 1A outputs.

The 0.5A range feature an input range of 6.5-36V DC and outputs of 3.3, 5, 12 and 15V DC which can be configured to provide either a positive or negative voltage. The 1A range features an input range of 6-36V with the same output voltages available.

Output features include a typical voltage accuracy of±2%, line regulation of±0.2%, load regulation of±0.6% (0.5A models) &±0.4% (1A models) for 10-100% load, continuous (self-recovering) short circuit protection and low ripple & noise (typically 20mV pk-pk, 20Mhz bandwidth).

Efficiency is up to 95% and the operating temperature range is -40°C to +85°C. There are four different mechanical formats for the 0.5A models, open frame thru-hole, ultra-miniature thru-hole, SMT part and a new variant that is fitted with wires. The 1A models are available as either open frame thru-hole part or SMT. All parts, excluding the open frame devices, are housed in a UL94 V-0 rated package.

The entire R3 Switching Regulator range meet latest safety and EMC standards and have an MTBF of 2000K hours. These devices are suitable for a wide range of applications including POL architectures, IOT devices, industrial control systems, instrumentation and general electronics.
