The TPS62850x-Q1 is a family of pin-to-pin 1A, 2A (continuous), and 3A (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 2A continuous output current and 3A peak current. In the TPS62850x-Q1, the switching frequency is externally adjustable from 1.8MHz to 4MHz. 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 an SOT583 package.

TIPA-050022 — Mobileye EQ6L 分離式電源供應設計

此電源設計是適用於 Mobileye EyeQ6Lite® SoC 的 TI 半離散式電源樹狀結構測試報告摘要。自動駕駛輔助系統 (ADAS) 等汽車應用採用 Mobileye EyeQ6L 等 ADAS 網域控制器處理器。這些精密的處理器需要在極低的電壓下具有非常高的電流。這些處理器也需要非常快速的輸出電壓暫態響應，以因應處理器負載電流的步進變化。

此電源供應器設計以有效率、符合成本效益的方式滿足快速暫態響應的嚴格要求。下圖所示的半離散方法，結合了 PMIC 和離散式穩壓器，可將負載點轉換器放在最佳位置，同時仍提供具有最小輸出電容的小型解決方案尺寸。
