LMR61428XMM/NOPB TI DC-DC Converter | 8-VSSOP | 2.7V-14V Input, 600mA Output

Product Overview

The LMR61428XMM/NOPB is a high-efficiency, step-up DC-DC converter from Texas Instruments, designed for compact power solutions. It operates from an input voltage range of 2.7V to 14V and delivers up to 600mA output current. Housed in an 8-pin VSSOP package, this device integrates a 1.4A, 0.2Ω internal switch, enabling high efficiency and minimal external components. The switching frequency is fixed at 1.6MHz, allowing the use of small inductors and capacitors, making it ideal for space-constrained applications.
