TPS2553DRVR – TEXAS INSTRUMENTS

The TPS2553DRVR is a Texas Instruments 4-channel, low-side, current-mode power switch designed for high-efficiency power distribution in portable and space-constrained applications. It operates from a 4.5V to 28V input voltage range, delivering up to 2A per channel with a total current limit of 6A. Each channel incorporates independent enable pins and features overcurrent, overtemperature, and undervoltage lockout protection. The device utilizes a proprietary current-mode architecture minimizing power loss during switching transitions, resulting in improved efficiency compared to traditional linear regulators, particularly at higher loads. Packaged in a space-saving 24-pin WSON (WQFN-24) package, it’s ideal for battery-powered devices requiring multiple independent power rails. Common use cases include powering multiple peripherals in smartphones, tablets, and other portable electronics, where its high efficiency and compact size are crucial. The integrated protection features simplify design and enhance system reliability, eliminating the need for external current-limiting components in many applications. Its fast transient response ensures stable power delivery even under fluctuating load conditions.
