Standard USB-C ports output a safe 5V by default, but this brilliant little \"decoy\" chip communicates directly with the charger's smart circuitry to request higher voltages—specifically 9V, 12V, 15V, or even 20V. It is the absolute best way to modernize your gear, allowing you to power smart soldering irons, FPV LiPo chargers, or wireless routers using a single, universal USB-C cable.\u003c\/p\u003e\n\u003cp\u003eWhether you are designing a custom field-charging case for your drone batteries or upgrading legacy DC-barrel devices to Type-C, the CH221K drastically simplifies the process. It automatically negotiates the highest supported voltage or a specific voltage set by the circuit design. Requiring virtually no external components, this microscopic chip fits onto the tiniest of adapter boards, saving critical space while safely unlocking up to 100W (20V @ 5A) of power from compatible chargers.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMulti-Voltage Triggering:\u003c\/b\u003e Easily configures standard USB-C PD or Quick Charge (QC) power supplies to output 5V, 9V, 12V, 15V, or 20V.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eUSB-C Modernization:\u003c\/b\u003e The perfect IC for converting older 12V or 20V DC-jack electronics to the modern, universal Type-C standard.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHigh Power Unlocked:\u003c\/b\u003e Capable of negotiating up to 100W of power delivery (depending on the source charger and e-marked cable capabilities).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMinimalist Integration:\u003c\/b\u003e Requires extremely few external components, making it incredibly easy to integrate into DIY PCBs and tight enclosures.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePart Number:\u003c\/b\u003e CH221K\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eIC Type:\u003c\/b\u003e USB PD \/ QC Sink Controller (Decoy \/ Trigger Chip)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSupported Voltages:\u003c\/b\u003e 5V, 9V, 12V, 15V, 20V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSupported Protocols:\u003c\/b\u003e USB Power Delivery (PD), Quick Charge (QC)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePackage Type:\u003c\/b\u003e Miniature SMD Package (typically SOT-23-6)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RC-LIFE","offers":[{"title":"Default Title","offer_id":54285755711826,"sku":null,"price":1.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1065\/8067\/2850\/files\/221.jpg?v=1786961045","url":"https:\/\/rc-life.com\/products\/ch221k-usb-pd-qc-fast-charge-trigger-controller-5v-20v-decoy-ic","provider":"rc-life","version":"1.0","type":"link"}
