TPS62877B1QWRZVRQ1 TI Buck Converter | 24-WQFN-FCRLF (4.05x3.05) | 2.7V-6V Input, 1A Output

Product Overview

The TPS62877B1QWRZVRQ1 from Texas Instruments is a high-efficiency, synchronous step-down (buck) converter designed for automotive and industrial applications. It operates over a wide input voltage range of 2.7V to 6V and delivers up to 1A of continuous output current. The device is housed in a compact 24-pin WQFN-FCRLF package measuring 4.05mm x 3.05mm, making it ideal for space-constrained designs. With integrated MOSFETs and a fixed switching frequency of 2.2MHz, the TPS62877B1QWRZVRQ1 achieves excellent transient response and low output ripple. It features advanced power-saving modes, including pulse frequency modulation (PFM) for light-load efficiency, and supports 100% duty cycle for low dropout operation. The device is AEC-Q100 qualified for automotive applications.
