Texas Instruments TPS62850x/TPS62850x-Q1 Step-Down Converters

Texas Instruments TPS62850x/TPS62850x-Q1 Step-Down Converters are a family of pin-to-pin 1A and 2A high efficiency, easy-to-use synchronous step-down DC/DC converters. These devices are based on a peak current mode control topology. The devices are designed for automotive applications such as infotainment and Advanced Driver Assistance Systems. Low resistive switches allow up to 2A continuous output current at high ambient temperature. The switching frequency is externally adjustable from 1.8MHz to 4MHz and can also be synchronized to an external clock in the same frequency range. In PWM/PFM mode, the TPS62850x/TPS62850x-Q1 automatically enters Power Save Mode at light loads to maintain high efficiency across the whole load range. The Texas Instruments TPS62850x/TPS62850x-Q1 provides a 1% output voltage accuracy in PWM mode, which helps design a power supply with high output voltage accuracy. The TPS62850x/TPS62850x-Q1 is available in a SOT583 package. The TPS62850x-Q1 devices are AEC-Q100 qualified for automotive applications.
