TPS62177DQCT General Description

The TPS62177DQCT is a synchronous step-down DC-DC converter manufactured by Texas Instruments. It's designed to provide efficient power conversion for battery-powered applications, especially in portable and handheld devices.This converter operates with a wide input voltage range of 3V to 17V, making it suitable for various battery chemistries and configurations. It offers an adjustable output voltage range from 0.9V to 6V, allowing flexibility in meeting different system requirements.With its integrated synchronous rectifier, the TPS62177DQCT achieves high efficiency levels, minimizing power loss and extending battery life. Its peak efficiency can reach up to 95%, contributing to longer device operation on a single charge.The device incorporates various protection features such as thermal shutdown, overcurrent protection, and undervoltage lockout to ensure system reliability and durability. These protections safeguard both the converter and the connected load from potential damage under fault conditions.The TPS62177DQCT comes in a small 3mm x 4mm HotRod™ QFN package, which facilitates space-saving designs in compact applications. Its low-profile design and minimal external component count make it ideal for space-constrained environments.
