Half-brick convertors need little
cooling
Ideal for engineers designing low-airflow high-temperature, 48V power architectures, for telecomms, wireless, industrial and many other applications.
Lambda has expanded its half-brick DC/DC convertor lineup with the introduction of the new iHG series Providing exceptional thermal performance, using the industry-standard half-brick footprint with no baseplate, these modules are ideal for engineers designing low-airflow high-temperature, 48V power architectures, for telecomms, wireless, industrial and many other applications

General-purpose power supplies boost efficiency
The LS50, LS75 and LS100 have 88 to 264V AC inputs, while the LS150 is switch-selectable for 115 or 230V AC, minimising the cost.
Power supplies cater for short-term peaks
Units provide a very cost and space efficient solution compared with oversizing conventional power supplies just to handle the peak current.
The initial product offering within the iHG family includes 5V/10A, 5V/20A and 3.3V/30A devices, with further products planned.
The single board construction combined with up to 93% efficiency delivers a very high level of useable power in convection cooled environments, particularly where airflow rates are low.
Furthermore, the all new digital control circuitry bringing a significant component count reduction, as well as improved reliability and lower cost, makes the iHG family well suited as replacements or upgrades in legacy applications.
The field-proven power conversion circuitry of the iHG family guarantees the product's monotonic start up into a highly capacitive, pre-biased load and no reverse current flow in standby, startup, shutdown or parallel operation uses.
In addition, a double-ended powertrain topology with FET driven synchronous rectification combined with a secondary side auxiliary control rail ensures safe operation under all functional and fault conditions.
This makes Lambda's iHG a more robust and higher reliability convertor than other modules available on the market, offering the ideal solution for powering a broad range of reliability critical applications.
In addition to high efficiency operation, the iHG's very low input current consumption in standby mode, demonstrates Lambda's commitment to the "green" environmental issues of concern to all designers in every application today.
The input is fully isolated from the output further adding to product versatility by allowing different options for polarity and grounding connectivity.
Standard features include fixed frequency operation, output trim, remote sense, remote on/off, and automatic recovery of input undervoltage, output overcurrent, overtemperature and overvoltage protection circuitry.
Latching/nonlatching protection and positive polarity on/off are offered as options.
Safety approvals for the iHG family include UL60950 (USA and Canada), VDE0805, CB scheme (IEC950) and CE Mark (EN60950). Request a free brochure from Lambda ...
