LTRIM DC-DC Converter IP Targeted for Single-Cell SoC Designs
LTRIM Technologies has announced the new LTR2500-T13M Li-ion battery compatible dc-dc converter IP block, which is now available in TSMC CMOS mixed-signal/RF 0.13-micron technology. The new high efficiency, synchronous step-down (buck) dc-dc converter IP block is intended for power management solution for system on chip (SoC) designs powered by Li-ion or three-cell alkaline battery powered applications. The LTR2500-T13M dc-dc converters give designers the ability to integrate power management into their SoCs to improve system performance and extend battery life while reducing overall cost and PCB area.
The LTR2500-T13M includes many features that make it especially useful for a wide range of SoC designs targeted at battery-powered devices. The wide input voltage range (2.5 to 5.0V) enables SoC designers to use popular Li-ion and/or three-cell alkaline batteries in their designs. The IP block provides a constant output voltage while operating across the complete Li-ion battery's range. The LTR2500-T13M operates at an efficiency of up to 92 percent, and includes SLEEP mode for light load operation and SHUTDOWN mode for power savings.
"There's a veritable cornucopia of portable devices on the market – from consumer products such as PDAs and digital cameras – to portable instrumentation and medical equipment, and typically they're powered by 3.6V Li-Ion or 4.5V three-cell alkaline batteries," said Sean Long, LTRIM's Director of Marketing. "Designers can use LTRIM's new LTR2500-T13M Li-Ion compatible DC-DC converter IP for power management and reap the benefits of noise reduction, longer battery life, and improved performance."
The LTR2500-T13M provides output voltages from 1.2 to 1.8V with a guaranteed output current of 100mA. LTRIM's new LTR2500-T13M step-down dc-dc converter is easily integrated into mixed-signal SoCs and analog ICs for overall bill of materials (BOM) cost savings, higher reliability and performance, and exceptional accuracy.
The LTR2500-T13M is available now in TSMC CMOS mixed signal/RF 0.13-micron technology; however, it can be retargeted to other foundry process technologies and output voltages.
