Frequently Asked Questions
What is the input voltage range of the LM2698MM-ADJ/NOPB?
The LM2698MM-ADJ/NOPB accepts an input voltage range of 2.2V to 12V, with a nominal operating point of 2.7V, making it well suited for single-cell Li-ion and multi-cell alkaline battery applications.
What is the maximum switch current of the LM2698MM-ADJ/NOPB?
The device features a 1.35A peak switch current rating. This current-mode PWM boost regulator uses pulse width modulation to regulate the output, providing inherent cycle-by-cycle current limiting for robust protection.
What package does the LM2698MM-ADJ/NOPB use, and what does the NOPB suffix mean?
It is housed in an 8-pin Small Outline package (MSOP-8 / S-PDSO-G8), which is a compact surface-mount package. The NOPB suffix indicates the device is lead-free (Pb-free), compliant with RoHS environmental regulations.
How is the output voltage set on the LM2698MM-ADJ/NOPB?
The output voltage is adjustable via an external resistor divider connected to the feedback pin. By selecting the appropriate resistor values, designers can set the desired output voltage to match their specific application requirements.
What are typical applications for the LM2698MM-ADJ/NOPB?
This boost regulator is commonly used in portable electronics, LED backlighting, USB power supplies, handheld test equipment, and any application that requires a regulated voltage higher than the available supply rail, particularly from low-voltage battery sources.
