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