The TPS6215x family is an easy-to-use synchronous step down dc-dc converter optimized for applications with high power density. A high switching frequency of typically 2.5 MHz allows the use of small inductors and provides fast transient response as well as high output-voltage accuracy by the use of DCS-Control topology.

With their wide operating input-voltage range of 3 V to 17 V, the devices are ideally suited for systems powered from either Li-Ion or other batteries as well as from 12-V intermediate power rails. The devices support up to 1-A continuous output current at output voltages between 0.9 V and 6 V (in 100% duty-cycle mode). The soft-start pin controls the output-voltage start-up ramp, which allows operation as either a standalone power supply or in tracking configurations. Power sequencing is also possible by configuring the enable (EN) and open-drain power-good (PG) pins.

In power-save mode, the devices draw quiescent current of about 17 µA from VIN. Power-save-mode, entered automatically and seamlessly if the load is small, maintains high efficiency over the entire load range. In shutdown mode, the device turns off and current consumption is less than 2 µA.

The device, available in adjustable- and fixed-output-voltage versions, comes in a 16-pin VQFN package measuring 3 × 3 mm (RGT).

TIDA-050001 — HDMI 2.0 ESD 保護參考設計

此參考設計展示兩種不同的方式,以保護 HDMI 2.0 驅動器與重定時器的 TMDS 線路,使其免受靜電放電 (ESD) 影響。HDMI 標準適用於從機上盒到筆記型電腦到電視的多項應用領域。由於這些連接埠始終是外部埠,因此容易受到 ESD 事件的影響。高速 HDMI 2.0 訊號代表驅動器無法在 IC 中整合良好的 ESD 防護,因此需要離散式 ESD 防護裝置。HDMI 驅動器通常也非常敏感,這表示 ESD 保護必須具有超低鉗位。此設計會檢查兩種設定的初始 HDMI 2.0 規範資料,每塊電路板上執行的 ESD 測試和測試後的最終 HDMI 2.0 規範資料。如需有關保護 HDMI (...)
