The TPS62852x-Q1 are a family of pin-to-pin, 1A, 2A, and 3A, high efficiency, easy-to-use, synchronous step-down DC/DC converters. These devices are based on a peak current mode control topology and support tight switching frequency variation. These devices are designed for automotive applications such as infotainment and advanced driver assistance systems. Low resistive switches allow up to 3A continuous output current. In the TPS62852x-Q1, the switching frequency is internally fixed at 2.25MHz. The TPS62852x-Q1 automatically selects pulse width modulation (PWM) for higher power demand and pulse frequency mode (PFM) for power saving operation. This selection maintains high efficiency across the whole load range. The device exists also in options with forced PWM in cases where frequency stability requirements dominate. The family provides a 1% output voltage accuracy over the full temperature range in PWM mode, which helps designing power supplies for devices with very tight supply voltage accuracy requirements.

The TPS62852x-Q1 is available in an 8-pin, 2.0mm × 1.5mm, WSON package.
