In addition to our switching regulators PSR-78xxLF and PSR1-78xxLF in a SIP3 case with 500 mA and 1000 mA we can now also offer a 500 mA switching regulator with an input of 4.5 – 28 V DC and output of 3.3 to 15 V DC in a SMD type case.
The very high efficiency (83~93%) is the determining feature of these new dc/dc switching regulators.
- Long-term short circuit proof
- Wide input voltage range
- Operating temperature area of -40C to +85C (without additional cooling) are only some of the new key features of the PSR series. They are 100% Pin-to-Pin compatable with standard linear regulators.
