MP1430:1.22V feedback voltage, 3A load single-chip integrated DC-DC high-efficiency buck converter chip, MP1430 operating voltage is (6V ~ 28V), operating frequency up to 385KHz, so that you can choose a relatively small inductance capacitor and cooperate with it to achieve small ripple output; The MP1430 has fewer peripheral components and can continuously output current up to 3A, with overtemperature\/overcurrent and short circuit protection.
In addition, by adjusting the feedback resistance, the output voltage of MP1430 can be adjusted arbitrarily, and the overcurrent protection point can be adjusted through an external resistance, and the operating frequency can be automatically reduced when the output short-circuit to make the output power smaller; The MP1430 can be widely used in battery voltage conversion and power conversion circuits for various devices, such as portable DVDS, LCDS, vehicle appliances, routers, digital photo frames, set-top boxes, network switches, etc.
