The Texas Instruments TPS5420QDRQ1 is a high-efficiency, 2A continuous output current, step-down (buck) converter designed for automotive applications. It features a wide input voltage range from 5.5V to 36V, making it suitable for various power management needs.
This device operates at a fixed 500kHz switching frequency, enabling the use of small external filters. The TPS5420QDRQ1 offers an adjustable output voltage down to 1.22V with 1.5% initial accuracy. Key features include internal compensation to minimize external component count, overcurrent limiting, overvoltage protection, and thermal shutdown for system protection.
Packaged in an 8-pin SOIC package, the TPS5420QDRQ1 is designed for surface mounting. Its operating temperature range is -40°C to 125°C (TJ), and it boasts high efficiency up to 95% thanks to an integrated 110mΩ MOSFET switch.
This converter is qualified for automotive applications and provides improved line regulation and transient response through input voltage feed-forward. It is suitable for designs requiring reliable power conversion within a broad voltage range.
