The IQ24280HEC14 and IQ24280HZC18 offer a nominal 28V output at 400W and 500W respectively, while the IQ24500HEC08 and IQ24500HZC10 offer a nominal 50V output at the same power levels. All devices utilise the industry standard half brick pin-out, and are completely encapsulated in a package measuring  2.49” x 2.39” x 0.512” to enable use in harsh environments requiring protection to the Pollution Degree 3 limits of EN/UL60950-1.

The devices offer high power densities of up to 164W/in3, and efficiencies of up to 95%. They offer the system designer valuable board area reductions of up to 42% over competitive full brick systems and the efficiency improvements over those devices are more than 7%, leading to a 60% reduction in power dissipation. This enables the designer to dramatically reduce the heat generated in the system and associated cooling mechanisms, as well as substantially improving overall system reliability.

Calculated MTBF figures according to MIL-HDBK 217F are 1.8Mhrs. All devices are capable of withstanding transients of 50V for 100ms, and have a basic isolation level from input to output of 2250Vdc. Control and protection features include input under-voltage lockout, output over voltage protection, current limit, short circuit protection and thermal shutdown. Full operating temperature range of the device is -40 to +100ºC, and it is fully RoHS 6/6 compliant.

Suitable for use in wireless technology platforms such as GSM, 3G, WiMAX and TD-SCDMA. Other targeted markets include electronic countermeasure applications such as RF jammers to counter remote controlled improvised explosive devices (RCIED’s), military communication equipment, and homeland security applications.

Key semiconductor technologies used in these areas include lateral diffused metal oxide semiconductor (LDMOS), gallium arsenide (GaAs) and gallium nitride (GaN) power transistors. These transistors typically need a supply voltage centered on either 28V or 50V, but the supply voltage needs to be optimised for each individual application.

The 28V IQ24280HxC devices offer an output trim range of -50% to +20%, while the 50V IQ24500HxC devices offer a trim range -50% to +10%, thereby covering a multitude of different requirements.

Sample and production quantities are available immediately with a stock to 12 week lead-time. The IQ24xxxHECxx and IQ24xxxHZCxx series are priced at $185.60 and $231.60 respectively in 1,000 quantities.
