The TPS624xx-Q1 family of devices are synchronous dual step-down DC-DC converters for Automotive applications such as Advanced Driver Assistance Systems (ADAS). They provide two independent output voltage rails powered by a standard 3.3-V or 5-V voltage rail, with fixed output voltages optimized for powering the CMOS imager or serializer-deserializer in ADAS camera modules.
The EasyScale™ serial interface allows output-voltages modification during operation. The fixed-output-voltage versions TPS624xx-Q1 support one-pin-controlled simple dynamic voltage scaling for low-power processors.
The TPS624xx-Q1 family of devices operates at 2.25-MHz fixed switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load-current range. For low-noise applications, one can force the devices into fixed-frequency PWM mode by pulling the MODE/DATA pin high. The shutdown mode reduces the current consumption to 1.2-µA, typical. The devices allow the use of small inductors and capacitors to achieve a small solution size.
