The product family PMG/PCMG with DC input voltage completes the range of primary switched MTM Power Modules. The modules offer an input range of 20...72 VDC and allow - due to the different types available in this series - efficient solutions in numerous application fields. They are available with single, dual or triple outputs. The single and dual (sym.) versions are UL 60 950 and UL 508 approved. Dimensions are 90,5 x 65,5 x 33,5 mm for PCB-mounting (PMG) and 120,0 x 65,5 x 33,0 mm for chassis mounting (PCMG). Thus, they offer the same dimensions and pinning as the standard AC/DC and low voltage modules of the same wattage range which allows the customer to design only one layout for standard AC, low voltage and DC input. The vacuum encapsulated devices offer an isolation of 3,3 kVrms and comply to the up-to-date EN standards as regards CE conformity. Further features are rugged design, SMD-technology, automatic 100 % final test and 100-%-burn-in-test. The series PMG/PCMG offers 15 W or 30 W constant output wattage, is short circuit protected and needs no ground load.

Compact DC/DC converters for DIN rail and wall mounting
At 100 Watt and 500 Watt the latest DC/DC converters from Zentro Elektrik extend the existing comprehensive range of converters.
The compact DC/DC converters are designed for applications in automation engineering, power supply and power station engineering, in traffic systems and railway in particular, and in mechanical engineering. They are air-cooled and have many control, operating and display elements.
Connections are made by means of easy-to-use screw terminals.
The converters are distinguished by a high degree of efficiency of > 80% and comprehensive protective and control facilities such as protection from overload and overvoltage, thermal protection and decoupling diodes. Options such as a varistor at the output, to prove additional overvoltage protection or a signal relay, further distinguish the
GWH 100 / 500 series of converters. Up to 3 units with active current sharing can be switched in parallel to extend power.

XP Power announces its JCA series of miniature, board-mounted low power DC/DC converters. Measuring just 1 x 0.8 x 0.4 inches (25.4 x 20.3 x 10.0 mm), the device's shielded metal package is 0.25 inches (6.4 mm) shorter than the 1.25 inch (31.8 mm) industry norm. Using the customary 24-pin DIP layout, the units occupy 20% less printed circuit board area than traditional products. This allows designers to reduce the size of new developments or add in more features, while maintaining the industry standard pin-out makes the converter an ideal drop-in replacement for existing designs.

The AIC1845 is a micropower charge pump DC/DC converter that produces a regulated 5V output. The input voltage range is 2.7V to 5.0V. Extremely low operating current (13uA typical with no load) and a low external-part count (one 0.22uF flying capacitor and two small bypass capacitors at VIN and VOUT ) make the AIC1845 ideally suitable for small, battery-powered ap-plications.
The AIC1845 operates as a PSM (Pulse Skip-ping Modulation) mode switched capacitor volt-age doubler to produce a regulated output and features with thermal shutdown capability and short circuit protection.
The AIC1845 is available in a 6-pin SOT-23 package.

The AIC1579 is a high-power, high-efficiency voltage-mode DC/DC controller for motherboard VI/O power supply applications. Designed to drive an N-channel MOSFET in a standard buck topology, the AIC1579 features a high voltage CMOS output driver, short-circuit protection, and 8-pin package.
An external 4-bit Digital-to-Analog Converter (DAC) can be used along with the AIC1579 to adjust the output voltage from 2.0V to 3.5V in 0.1V increments. Table 1 on the following page specifies the corresponding output voltage for 16 combinations of DAC inputs as in the typical application circuit.
The 200KHz switching frequency allows for using small external components while maintaining high conversion efficiency. The 11MHz bandwidth and 6V/uS slew rate of the error amplifier ensures high converter bandwidth and fast transient response.
The AIC1579 provides adjustable overcurrent and short-circuit protections by sensing the output current across the on resistance of the external N-channel MOSFET rather than an external low value sense resistor.
The AIC1579L provides lower reference voltage (1.30V) than the default (2.00V, AIC1579) for lower VOUT requirement.

The AIC1638 is a high efficiency step-up DC/DC converter for applications using 1 to 4 NiMH battery cells. Only three external components are required to deliver a fixed output voltage of 2.7V, 3.0V, 3.3V, 4.5V or 5V. The AIC1638 starts up from less than 0.9V input with 1mA load. Pulse Frequency Modulation scheme brings optimized performance for applications with light output loading and low input voltages. The output ripple and noise are lower compared with the circuits operating in PSM mode.
The PFM control circuit operating in 100KHz (max.) switching rate results in smaller passive components. The space saving SOT-23, SOT-89 and TO-92 packages make the AIC1638 an ideal choice of DC/DC converter for space conscious applications, like pagers, electronic cameras, and wireless microphones.
