Micropackage step-down regulators available up to 20A

     Using the latest circuitry and manufacturing technology, RECOM offers a range of low-cost packaged step-down regulators in ultra-compact, heat-enhanced LGA and QFN packages with output current grades 1,3,10 and 20A. All of these products feature integrated magnetism, including remote on/off, good power signal, and comprehensive protection against input undervoltage, overtemperature, short circuit, and output overload.

     The RPL-1.0 has a 3 mm x 3 mm LGA footprint and is only 2 mm high. It has an input range of 3V to 22V and an output. The RPL-1.0 has a 3 mm x 3 mm LGA footprint and is only 2 mm high. It has an input range of 3V to 22V and an output range of 0.6V to 12V. Depending on the input/output voltage combination, Range of 0.6V to 12V. Depending on the input/output voltage combination, the 1A output can be used for ambient temperatures in excess of 80 ° C and can operate up to 125 ° C with derated ambient temperatures. Up to 95% efficiency.

     The RPH-3.0 comes in 47 pad QFN packages with a footprint of 10mm x 12mm and a height of 4mm. It offers 3A outputs in an input range of 4.5V to 55V, and offers an adjustable output range of 1V to 15V. Efficiency up to 91%, for example, at 12Vin and 3.3Vout, the full output current can reach more than 80C.

     Part of the RPL-10 is rated at 10A output and is rich in features. In the LGA-M package of just 7mm x 7mm and 4.4mm high, the regulator has an input range of 4V to 16V and a programmable output of 0.6V to 5.5V. Efficiency up to 94%, allowing operation up to 90 ° C at full load. The operating frequency is optional between 600kHz and 800kHz, the control is fast transient response through constant on-time, and the pulse jump mode maintains efficiency under light loads.

     Finally, the RPL-20 takes power density to a new level with programmable outputs from its 20A rating of 0.6V to 5.5V. The input range is 4V to 16V, the efficiency is up to 94%, and it can work at full load at 90C. The package size is the same as the RPL-10 at 7mm x 7mm and 4.4mm high, effectively doubling the power density. The operating frequency can be set between 600kHz and 1MHz, and the forced continuous conduction and pulse jump modes are optional.

     RECOM's M.Sc. DC-DC product Manager, Matthew Dauterive, commented, "These buck converters are ideal for use in tight spaces where high efficiency is required. "They excel in applications such as portable devices, imaging systems, distributed power architectures, fgpa power supplies, and general telecommunications and industrial uses."
