The TPS62816-Q1 is a pin-to-pin high efficiency, easy-to-use synchronous step-down DC/DC converter. It is based on a peak current mode control topology. It is designed for automotive applications such as infotainment and advanced driver assistance systems. Low resistive switches allow up to 6-A continuous output current. 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 TPS62816-Q1 automatically enters power save mode at light loads to maintain high efficiency across the whole load range. The TPS62816-Q1 provides a 1% output voltage accuracy in PWM mode, which helps design a power supply with high output voltage accuracy. The SS/TR pin allows setting the start-up time or tracking of the output voltage to an external source. This allows external sequencing of different supply rails and limiting the inrush current during start-up.

The TPS62816-Q1 is available as an adjustable version, packaged in a 3-mm × 2-mm VQFN package with wettable flanks.
