Texas Instruments TPS6244x/TPS6244x-Q1 Dual Step-Down Converters are pin-to-pin dual 1A, dual 2A or 3A, and 1A high-efficiency and easy-to-use synchronous step-down DC/DC converters. The TPS6244x/TPS6244x-Q1 is based on a peak current mode control topology and designed for automotive applications such as infotainment and advanced driver assistance systems. The low resistive switches enable up to 3A continuous output current and a maximum output current of up to 4A at high ambient temperature. The switching frequency is externally adjustable from 1.8MHz to 4MHz and can also be synchronized to an external clock from 2MHz to 4MHz.
The TI TPS6244x/TPS6244x-Q1 Converters in PWM and PFM mode automatically enter power save mode at light loads to maintain high efficiency across the whole load range. The TPS6244x/TPS6244x-Q1 provides a 1% output voltage accuracy in PWM mode, which helps design a power supply with high output voltage accuracy.
The TPS6244x/TPS6244x-Q1 is offered as an adjustable voltage version, packaged in a VQFN package. The TPS6244x-Q1 devices are AEC-Q100 qualified for automotive applications.
