♠ LM2775 Hoʻololi i ka Capacitor 5-V Boost Converter

ʻO ka LM2775 kahi mea hoʻololi pālua-capacitor i hoʻoponopono ʻia e hoʻopuka ana i ka uila puka haʻahaʻa haʻahaʻa.Hiki i ka LM2775 ke hāʻawi aku i ka 200 mA o ka manawa hoʻopuka ma luna o ka 3.1-V a i ka 5.5-V hoʻokomo, a hiki i ka 125 mA o ka manawa hoʻopuka i ka wā e like me ka haʻahaʻa o ka volter input e like me 2.7 V. Hiki i ka LM2775 ke hoʻemi i kona manawa mālie ma ka hana ʻana i ke ʻano pulse frequency modulation (PFM).Hiki ke hoʻohana ʻia a hoʻopau ʻia ke ʻano PFM ma ka hoʻokele ʻana i ka pine PFM i kiʻekiʻe a haʻahaʻa paha.Eia hou, i ka wā e pani ʻia ai ka LM2775, hiki i ka mea hoʻohana ke koho e huki i ka volta puka i GND a waiho ʻia paha i kahi kūlana impedance kiʻekiʻe ma ke kau ʻana i ka pine OUTDIS kiʻekiʻe a haʻahaʻa paha.

Ua hoʻokomo ʻia ka LM2775 i ka 8-pin WSON o TI, kahi pūʻolo me nā waiwai wela maikaʻi e mālama ai i ka ʻāpana mai ka wela ma lalo o nā kūlana hana i helu ʻia.
