TPS54302DDCR step-down converter
The TPS54302DDCR is a high-efficiency synchronous step-down (buck) converter from Texas Instruments, delivering up to 3A continuous output current with an exceptionally wide input voltage range of 4.5V to 28V in a compact SOT-23-6 (TSOT-23-6) package measuring just 2.9mm × 1.6mm. This advanced DC-DC converter integrates both high-side (85mΩ) and low-side (40mΩ) MOSFETs, achieving peak efficiencies up to 95% while minimizing external component count through internal loop compensation and a built-in 5ms soft-start function. Operating with a fixed 400kHz switching frequency and featuring frequency spread spectrum for EMI reduction, the device consumes only 45µA quiescent current and 2µA in shutdown mode, making it ideal for battery-powered and noise-sensitive applications. Characterized for industrial temperature range from -40°C to +125°C, this RoHS-compliant device provides robust thermal performance through an exposed pad design that enables efficient heat dissipation.
