Introduction to the LMR10510YSDE/NOPB

The LMR10510YSDE/NOPB is a IC buck-boost converter from Texas Instrument’s power management integrated circuit (PMIC) portfolio. This buck-boost converter can help maximize battery life in battery-operated applications. It is ideally suited for power path applications or power systems with a minimum supply voltage of 3.8 V. The converter regulates the output voltage to a very small tolerance, even under changing input and load conditions.

Application Fields of LMR10510YSDE/NOPB

The LMR10510YSDE/NOPB is a buck-boost dc-dc converter that can provide a steady output voltage over a wide input voltage range. It is suitable for a wide range of applications from automotive to industrial and from portable to application accessories. Automotive applications include camera modules, radar systems, and connectivity. Industrial applications include power path management or battery-powered device systems. Additionally, the LMR10510YSDE/NOPB finds its niche in a variety of portable and stationery products like remote controllers, chargers, and medical.

Working Principle of LMR10510YSDE/NOPB

The LMR10510YSDE/NOPB is a dc-dc converter designed on buck-boost topology. It can step up a low voltage input to a higher voltage output and even step down a high voltage input to a lower voltage output. This IC is designed to operate with input voltages from 3.8V to 40V and output voltages from 0.8V to 36V, which means it supports wide input-output voltage differences.The IC provides two modes of operation: forced PWM for high efficiency and forced PFM for low power consumption. The PWM switching frequency (Fsw) can be adjusted from 200 kHz to 1.3M Hz. The part includes a number of protection features such as UVLO, over-current protection (OCP) and over temperature protection (OTP). And the regulators support over temperature protection and short-circuit protection.

Conclusion

The LMR10510YSDE/NOPB is a versatile and reliable buck-boost converter designed by Texas Instrument, suitable for a wide range of applications from automotive to industrial and from portable to stationery products, while having a wide input voltage range of 3.8V to 40V and output voltage range of 0.8V to 36V. It supports two modes of operations such as forced PWM and forced PFM, suitable for efficiency and low power consumption, respectively. It also provides various protection features including UVLO, OCP and OTP.
