TPS62993-Q1 Automotive Buck Converter Texas Instruments TPS62993-Q1 Automotive Buck Converter offers high efficiency and flexibility in a small package size that is easy to use. The TPS62993-Q1 provides a 2.5MHz or 1.0MHz selectable switching frequency, permitting a fast transient response and using small inductors. The device delivers a high ±1.5% VOUT accuracy across the entire operating temperature range and enhanced load transient performance with the DCS-Control topology. The wide 3V to 10V input voltage range supports a variety of nominal inputs, such as 9V supply rails, single-cell or multi-cell Li-Ion, and 5V or 3.3V rails.
