Inexpensive low-power “AC/DC-Converter” with extremely low no-load power consumption
RECOM announced the release of a new range of isolated AC/DC power supply modules with very low standby input currents, ideally suited for low power applications or standby power supplies.
RECOM - Next Generation of R-78 switching regulator announced - the R-78C series
The existing features of the standard R-78 series (high efficiency, small case size & pin-compatibility with 78-series linear regulators) have been improved by adding a much higher input voltage range of up to 42VDC and double the output power in the same size case. The R-78C series offers 15W/cm³ of power.
DC/DC converters from Diodes Incorporated increase efficiency
Delivering a continuous load current of up to 3A the AP6507 and AP6508 synchronous DC/DC buck converters from Diodes Incorporated offer designers of distributed power systems an operating efficiency as high as 90%. With input voltage ranges of respectively 4.5V to 18V and 4.5V to 21V, these compact converters will support the needs of low voltage 5V and 12V bus systems in a broad range of consumer electronic products including monitors, LCD TVs ...
Powersolve’s Intelligent Charger can Charge up to 15 NiMH/NiCD Cells in Series
An intelligent battery charger that can automatically detect and charge 8 to 15 NiMH or NiCD cells is announced by leading power supply specialist Powersolve. The PSCH30 Smart Charger is “clever” enough to identify the number of cells in series and provide the necessary output to fully charge the cells and then turn itself off.

System for auto start-stop function in vehicles
ELMOS introduces a set of chips for the implementation of an automatic start-stop function in vehicles. With ELMOS chips E981.01 and E910.28, the voltage supply of the automotive on-board system can be maintained when car and engine stop in front of a red light or while passengers are getting in or out. This not only saves fuel but also improves the CO2 balance of the vehicles.
Robust automotive-grade buck regulator ICs with wide input voltage range
The new A8582 and A8583 from Allegro MicroSystems Europe are robust automotive-grade buck regulator ICs with high switching frequency and output current and a wide input voltage range. Each device integrates a low-resistance high-side N-channel MOSFET, and incorporates current-mode control to provide excellent loop stability and transient response.
