The continuously growing number of electric and electronic applications in vehicles demands constant and maintenance-free supply.
MTM Power has developed a new generation of DC/DC converters with 80 and 150 Watt output power; these converters are especially designed for applications in vehicle and rail technology but also for use in industrial and telecommunication applications. This new model range allows input voltages of 9/14.4...154 VDC, in various voltage ranges, thereby covering all common battery sets. Typical input voltage ranges are, among others, according to EN 50 155, 14.4...33.6 VDC (24 VDC nominal), 21.6...72 VDC (36/48 VDC nominal) and 43.2...154 VDC (72/110 VDC nominal). Input voltage ranges deviating from these can be realised specifically for the customer at any time.

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.

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.
