3 InstructionsThe TPS624xx-Q1 device family is a dual synchronous step-down DC-DC converter for automotive applications such as advanced driver assistance systems (ADAS). The series is available in two sets by Standard 3A separate output rail powered by a 3 V or 5 V rail, as well as an optimized fixed output voltage, power the CMOS imager or serializer-deserializer in the ADAS camera module. The EasyScale serial interface allows the output voltage to be modified during operation. The fixed output voltage version of the TPS624XX-Q1 enables simple dynamic voltage scaling with single-pin control of low-power processors. The TPS624xx-Q1 device family is available in 2Operates at a fixed switching frequency of 25 MHz and enters power-down mode at light load currents to maintain high efficiency over the entire load current range. For low-noise applications, the device can be forced into fixed-frequency PWM mode by pulling up the Mode Data pin. Shutdown mode reduces current consumption to 1Typical value of 2 a. This device allows the use of small inductors and capacitors, enabling a small solution size.
