The TPS62404QDRCRQ1 is a dual step-down DC-DC converter designed for automotive applications, qualified under AEC-Q100 with a temperature range of -40°C to 125°C. It operates with a fixed switching frequency of 2.25 MHz and supports input voltages from 2.5 V to 6 V. The device can deliver output currents of 400 mA and 600 mA, with adjustable output voltages ranging from 0.6 V to the input voltage. It features high efficiency, reaching up to 95%, and includes a power-save mode for light load conditions, maintaining a typical quiescent current of 32 µA. The TPS62404QDRCRQ1 also supports dynamic voltage scaling through a pin-selectable output voltage and offers 100% duty cycle operation for minimal dropout. This product is suitable for applications in infotainment systems and advanced driver-assistance systems (ADAS).
