Model Y1 — 12V to 13.8V Boost Regulator (Nonisolated), 1A Key benefits Provides a reliable, fixed 13.8V output from a 12V source to run or floatcharge equipment that expects a higher nominal voltage. Solves compatibility problems when devices require 13.8V but the available supply is a nominal 12V system (vehicle batteries, 12V leadacid banks, solar/auxiliary supplies). Small, boardmounted boost converter design delivers a stable output up to 1A without the complexity of isolation, making it simple to integrate into existing 12V systems. What it does Converts a 12V input to a regulated 13.8V output. Rated maximum output current: 1 ampere. Nonisolated boost topology: input and output share a common reference ground. Key attributes Model: Y1 Functionality: Stepup (boost) DCDC voltage regulator with fixed 13.8V output. Input/Output: Accepts nominal 12V input and supplies regulated 13.8V output at up to 1A. Isolation: Nonisolated (common ground between input and output). Form factor: Compact PCB module suitable for inline mounting inside equipment or enclosures. Use considerations: Designed for applications where isolation is not required and where a modest current boost is sufficient. Performance and compatibility Delivers a steady 13.8V output while supplying loads up to 1A. Ideal for devices that require a slightly higher voltage than typical 12V systems provide. Compatible with standard 12V sources such as vehicle batteries, 12V battery banks, and similar DC supplies. Because the converter is nonisolated, confirm commonground compatibility before connecting to systems that require galvanic isolation. Typical applications Powering 13.8V radio transceivers, CB/ham equipment, or communication devices from a 12V vehicle or battery system. Supplying a regulated 13.8V float voltage to electronics and accessories that perform at that nominal voltage. Providing the correct operating voltage for sensors, control modules, or small loads that specify 13.8V input. Installation and usage notes Observe correct input polarity. Nonisolated design means input and output grounds are the same—avoid connections that require isolation. Do not exceed the 1A output limit. Allow for adequate ventilation or mounting inside an enclosure that dissipates heat generated under load. Verify compatibility with the target device's voltage and grounding requirements before final installation. This Y1 12V→13.8V 1A boost regulator is a straightforward solution when you need a compact, dependable stepup converter to power 13.8V devices from common 12V sources.
