Description for the TPS628502-Q1
The TPS62850x-Q1 is a family of pin-to-pin 1-A, 2-A (continuous), and 3-A (peak) high efficiency, easy-to-use synchronous step-down DC/DC converters. These devices are based on a peak current mode control topology. These devices are designed for automotive applications such as infotainment and advanced driver assistance systems. Low resistive switches allow up to 2-A continuous output current and 3-A peak current. In the TPS62850x-Q1, the switching frequency is externally adjustable from 1.8 MHz to 4 MHz. The devices can also be synchronized to an external clock in the same frequency range. In PWM/PFM mode, the devices automatically enter power save mode at light loads to maintain high efficiency across the whole load range. The family provides a 1% output voltage accuracy in PWM mode which helps design a power supply with high output voltage accuracy.
The TPS62850x-Q1 are available in a SOT583 package.
