TPS62135RGXR

The TPS62135RGXR from Texas Instruments is an active step-down (buck) converter designed for efficient power management. It supports an input voltage range from 3V to 17V and can deliver a maximum output current of 4A. The output voltage is adjustable, ranging from 0.8V to 12V, with an accuracy of ±1% in PWM mode.

This converter operates with a typical switching frequency of 2.5MHz in forced PWM mode, contributing to its compact design and efficiency. It features a low quiescent current of 18µA typical, making it suitable for applications where power conservation is critical. The device includes features such as Enable, Light Load Efficiency, Output discharge, Power good, Pre-Bias Start-Up, Synchronous Rectification, Tracking, and UVLO.

The TPS62135RGXR is available in a 11-VQFN-HR package, measuring 3mm x 2mm, and is designed for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ). The control mode utilizes Constant on-time (COT) and DCS-Control, offering precise regulation and fast transient response.

Key features include Automatic Efficiency Enhancement (AEE™) and DCS-Control™ topology. It also supports 100% Duty Cycle Mode and has an adjustable soft-start function. The precise ENABLE input allows for user-defined undervoltage lockout, and the device offers exact sequencing capabilities. An optional HICCUP overcurrent protection is also available.
