Renesas Electronics America, a leading supplier of advanced semiconductor solutions, today expands its portfolio of Simple Power Supply ICs, with innovative 16V input capable synchronous buck regulators that deliver up to 3A continuous current to loads at voltages as low as 0.8V. The new power supply ICs are ideal for systems requiring even lower power consumption in standby mode, and systems requiring backup power in case of power outage. The devices target applications in the industrial, office equipment, consumer, networking, smart grid, and other fields.
By reducing the power supply design workload, the new devices lower power consumption and improve the compactness of the overall system for improved power efficiency and lower BOM cost. The new Simple Power Supply ICs are available in four series with different DC/DC converter output counts and output voltages. Battery backup functionality is availability in the: RAA23012X series, RAA23013X series, RAA23022X series, and the RAA23023X series. Each series comprises three product versions, for a total of 12 new devices.
“Power semiconductor advancements have created a dynamic environment for energy saving innovations that boost the efficiency of existing applications, the electrification of more applications, and improve energy transmission,” said William Keeley, senior director product marketing at Renesas Electronics America. “Engineers and designers can confidently look to these types of power devices we are announcing today as a source of opportunity as they design their next generation energy efficient systems and products.”
As systems become more power efficient and compact in recent years, demand has grown for power supply blocks with improved power efficiency delivered in a compact form factor. One commonly used method of reducing power consumption is to incorporate a low-power mode in which only the functions needed in the microcontroller’s (MCU) standby state continues to operate. Unlike MCUs, however, such measures are rarely implemented within the power supply block itself. The common method of using a pair of diodes to implement a battery backup circuit for devices such as SRAM and MCUs, which require power even when the system is powered down, makes it difficult to maintain a compact system. What is more, in systems that require two or more voltages, the usual method is to employ multiple single-output power supply ICs or electronic components, which also presents a barrier to compactness.
