3.3V升壓/降壓型穩壓器(S9V11F3S5CMA)

SSO0193

S9V11F3S5CMA開關升壓/降壓調節器可高效地產生固定的3.3 V或5 V輸出,無論它是高於還是低於輸入電壓,範圍可以從2 V到16 V. :最小啟動電壓為3 V,但之後它的工作電壓為2 V.調節器還具有防止電池過度放電的帶滯後功能,可精確調節的低壓切斷。 當輸入電壓接近輸出電壓時,緊湊型(0.5“×0.6”)模塊可以提供高達1.5 A的典型輸出電流。

產品簡介

The S9V11x family of efficient switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) use a buck-boost topology to convert both higher and lower input voltages to a regulated output voltage. They take input voltages from 2 V to 16 V and increase or decrease them as necessary, offering a typical efficiency of over 85% and a typical output current of up to 1.5 A. The flexibility in input voltage offered by this family of regulators is especially well-suited for battery-powered applications in which the battery voltage begins above the regulated voltage and drops below as the battery discharges. Without the typical restriction on the battery voltage staying above the required voltage throughout its life, new battery packs and form factors can be considered.

Identifying markings

PCB dev codes: reg20b
Other PCB markings: 0J10534

Notes:

  • Without included optional headers.
  • Note: the minimum startup voltage is 3V, but the regulator can operate down to 2V after startup.
  • Under typical conditions, where the input voltage is close to the output voltage. Maximum output current can be higher when stepping down and lower when stepping up.
  • Output can be changed to 5 V by driving the SEL pin over 1.1 V.
  • With no load. Actual quiescent current depends on input voltage; it is typically under 300 µA when the input voltage is close to the output voltage.
