Texas Instruments TPS62423QDRCRQ1
The TPS624xx-Q1 family of devices are synchronous dual step-down DC-DC converters forAutomotive applications such as Advanced Driver Assistance Systems (ADAS). They provide twoindependent output voltage rails powered by a standard 3.3-V or 5-V voltage rail, with fixed outputvoltages optimized for powering the CMOS imager or serializer-deserializer in ADAS cameramodules.
The EasyScale™ serial interface allows output-voltagesmodification during operation. The fixed-output-voltage versions TPS624xx-Q1 supportone-pin-controlled simple dynamic voltage scaling for low-power processors.
The TPS624xx-Q1 family of devices operates at 2.25-MHz fixed switching frequency andenters the power-save mode operation at light load currents to maintain high efficiency over theentire load-current range. For low-noise applications, one can force the devices intofixed-frequency PWM mode by pulling the MODE/DATA pin high. The shutdown mode reduces the currentconsumption to 1.2-µA, typical. The devices allow the use of small inductors and capacitors toachieve a small solution size.
