R-78AAxx-0.5SMD Series Switching Regulators (non-isolated)
The R-78AAxx-0.5SMD series are manufactured without lead and meet the requirements for RoHS 10/10 as well as the increased reflow soldering temperatures associated with vapor phase soldering, making these high efficiency switching regulators ideally suited to modern pick-and-place mass production. The efficiency of up to 97% means that very little energy is wasted as heat. The additional features of remote on/off control and adjustable output voltages will find many uses in the battery-powered, industrial, medical and automotive markets.
- Efficiency up to 95%, no need for heatsinks
- High reflow temperature SMD package
- Adjustable output voltage
- Wide input range (4.74V - 32V)
- Short circuit protection, thermal shutdown
- Remote on/off control
- very low shutdown current
- Certifications: CERT EN 55022, CERT EN 60950-1

AC/DC Converters
AC/DC-Power Supplies provide DC-Voltage to generations of electronic designs. Since the introduction of the EuP-Directive (energy saving products) in January 2010 the focus is on high efficiency. Particularly electronic devices with a standby- function require a small power supply to meet this directive. The modules of our AC-family provide 1 to 960 Watts power. They feature a high packing density, low no-load current and have an MTBF guaranteeing 40 years of continuous operation.
