R-78Bxx-1.0(L) Series Switching Regulators (non-isolated)
The R-78Bxx-1.0 series high efficiency switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible. The efficiency of up to 97% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs. The L-Version with 90° pins allows direct replacement for laid-flat regulators where component height is at a premium. Low ripple and noise figures and a short circuit input current of typically only 10mA round off the specifications of this versatile converter series.
- Efficiency up to 97%, no heatsinks required
- Pin-out compatible with LM78XX linears
- Low profile (L/W/H=11.5 x 8.5 x 17.5mm)
- Wide input range
- Short circuit protection, thermal shutdown
- Low ripple and noise
- "L" version with 90° pins
- Certifications: 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.
