The TC1682, TC1683 and TC1684 are CMOS charge pump converters that provide an inverted doubled output from a single positive supply. An on-board oscillator provides the clock and only three external capacitors are required for full circuit implementation. Switching frequencies are 12kHz for the TC1682, 35kHz for the TC1683, and 125kHz for the TC1684. When the SHDN pin is held at a logic high, the device goes into a very low power mode of operation consuming less than 1µA (typ.) of supply current. Low output source impedance (typically 120O), provides output current up to 10mA. The TC1682, TC1683 and TC1684 feature a 1.8V to 5.5V operating voltage range and high efficiency, which make them an ideal choice for a wide variety of applications requiring a negative doubled voltage derived from a single positive supply (for example: generation of -7.2V from a +3.6V lithium cell or -10V generated from a +5V logic supply).The minimum external part count, small physical size, and shutdown mode feature make this family of products useful for a wide variety of negative bias power supply applications.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
TC1682 is an authentic electronic component manufactured by Microchip, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official TC1682 datasheet above.
Electronic component spot-market pricing for TC1682 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for TC1682 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
