The Texas Instruments TPS65400QRGZRQ1 is an automotive-qualified quad synchronous buck converter designed for flexible power management. It accepts an input voltage range of 4.5 V to 18 V, supporting applications requiring robust power delivery.
This device features four switching regulators, with two capable of delivering up to 4 A each, and two capable of 2 A each. The output voltage is adjustable from 0.8 V up to 16 V, providing versatility for various system requirements. Key electrical features include a wide switching frequency range from 275 kHz to 2.2 MHz, adjustable current limit, and synchronous rectification for improved efficiency, which can reach up to 95% for each regulator.
Designed for surface mount installation, the TPS65400QRGZRQ1 comes in a 48-VQFN (7x7 mm) package with an exposed pad for enhanced thermal performance. Its operating temperature range is -40°C to 125°C (TJ). The device integrates multiple protection features such as undervoltage lockout (UVLO), overcurrent protection (OCP), and overtemperature protection (OTP) to ensure reliable operation in demanding automotive environments.
