CUI Introduces Next Generation 500 mA DC Switching Regulator Series
TUALATIN, Ore. – CUI Inc today announced its 2nd generation non-isolated dc switching regulator series rated at 500 mA. The company’s new P7805-S series implements several upgrades, including an increased power density, efficiency improvements and a decrease in ripple and noise, all at a lower per unit cost.
The series delivers efficiencies over 96% and is able to maintain a high efficiency rating across the full input range; still providing up to 95% efficiency at a highline input of 32 Vdc.
The P7805-S has been designed as a high performance, drop-in alternative to LMXX78 and LMXX79 linear regulators, eliminating the need for a heat sink. The devices are targeted at portable devices, battery-fed equipment, and embedded designs where board space is at a premium and energy efficiency is a concern.
The P7805-S series boasts a wide input range (4.75 to 32 Vdc), varying in line with the output voltage configuration. Output options include 1.5, 1.8, 2.5, 3.3, 5, 6.5, 9, 12, and 15 Vdc.
To address LMXX79 applications, CUI has designed all units in the series with the added capability of supporting a positive to negative voltage conversion, increasing the series’ flexibility.
The units are housed in a compact 3-pin TO-220 compatible SIP package measuring 11.60 x 7.50 x 10.20 mm and operate across an industrial temperature range of -40 to +85°C. Features include short circuit protection, over temperature protection, and an mean time between failures (MTBF) of 2 million hours.
Additionally, CUI has improved the ripple and noise performance across the input range to 20-30 mVp-p, this eliminates the need for LC filters on the output in many instances, further reducing board space and BOM cost.
The P7805-S series is available immediately with prices starting at $4.38 per unit for 500 pieces through distribution. Please contact CUI for OEM pricing.
