Delivering very high operating efficiencies over a wide range of load conditions, the TDK Innoveta iQE Series of Quarter Brick DC-DC converters from Lambda responds to the ever increasing demand for improved efficiency under all normal operating load conditions. With a broad range of output voltages from 3.3 to 15V and providing high power ratings, these DC-DC converters are ideal for engineers seeking excellent efficiency and optimal thermal performance for 24V and 48V power architectures in many applications within the industrial, telecommunications, data communications, access and wireless markets.
Lambda’s new single output iQE Series is rated at up to 204W, and offered with two input voltage ranges – either 18V to 36V or 36V to 75V. A key highlight to the DC-DC converters within Lambda’s iQE Series is the very high efficiency rating reaching up to 94%. What’s more, the efficiency curve remains high and incredibly flat, staying at more than 91% efficiency, under a wide 25% to 100% load.
Throughout the open frame, single board construction, particular attention has been made to the overall thermal design including component height, location and orientation. As a result, the iQE family is compatible with all cooling strategies, including contact, convection and forced air, and offers outstanding thermal performance for cooler operation over its operating temperature range of -40°C to +125°C.
Following on from the successful iQB range of Quarter Brick converters, the low component count on the iQE Series together with the planar magnetics provide reliability and a more cost-effective solution than many modules on the market. The iQE Series from Lambda features industry standard DOSA compatible pin out and quarter brick footprint, fixed frequency operation at 300kHz and low noise output for powering a broad range of applications including RF, DPA, POLs, FPGA, ASIC, DSP, Microprocessors, access, optical and industrial loads.
Further, the input is fully isolated from the output adding to the iQE’s versatility by allowing different output polarity and grounding connectivity. Standard features include remote sense, remote on/off, and auto recovery of input under voltage, output over voltage, output over current and over temperature protection circuitry. Positive polarity on/off is offered as an option.
iQE converters are approved to a wide range of national and international standards, including UL, CSA, VDE and CE, making it simple for users to obtain regulatory approval for equipment which incorporates them. With the addition of a few extra components, the units will also comply with EMC regulations to EN55022 Class A/B. In addition, Lambda’s entire iQE Series quarter brick family is RoHS compliant as standard. Samples are available now, with production quantities on standard lead times.
Lambda designs and manufactures power supplies for a wide range of applications including test and measurement, factory automation, process control, medical, communications, computing and COTS (commercial off-the-shelf). Lambda offers a comprehensive range of AC-DC power supplies and DC-DC converters, backed by fully-automated electronic assembly lines coupled with stringent testing procedures. Lambda is a unit of TDK Corporation (TDK ADR (NYSE) TDK (LON) TDK (BRU)) a leading global electronics company headquartered in Tokyo.
