Product Specification

3-V To 10-V TPS62992QRYTRQ1 2A low-IQ Automotive Synchronous Buck Converter

Product Description Of TPS62992QRYTRQ1
TPS62992QRYTRQ1 is a highly efficient, small, and flexible synchronous step-down DC-DC converter that is easy to use. A selectable switching frequency of 2.5 MHz or 1.0 MHz allows the use of small inductors and provides fast transient response. The device supports high VOUT accuracy of ± 1.5% across the entire operasting temperature range and enhanced load transient performance with the DCS-Control topology. The wide 3-V to 10-V input voltage range supports a variety of nominal inputs, like 9-V supply rails, single-cell or multi-cell Li-Ion, and 5-V or 3.3-V rails.
TPS62992QRYTRQ1 can automatically enter power save mode (if auto PFM or PWM is selected) at light loads to maintain high efficiency. Additionally, to provide high efficiency at very small loads, the device has a low typical quiescent current of 4 µA. AEE, if enabled, provides high efficiency across VIN, VOUT, and load current. The device includes a MODE/Smart-CONF input to set the internal and external divider, switching frequency, output voltage discharge, and automatic power save mode or forced PWM operation.
