220V-245V circuit module

Overview

DK112 and DK1203 are dedicated low-power switching power supply control chips that can implement power solutions within 12W (for example: 5V2.4A, 12V0.5A), and can be widely used in power adapters, LED power supplies, induction cookers, air conditioners, DVDs and other small household appliances .
These two chips, DK112 and DK1203, have built-in overcurrent protection circuits, anti-overload protection circuits, output short-circuit protection circuits, temperature protection circuits and optical coupling failure protection circuits. Compared with switching power supplies based on the RCC principle of discrete devices, or RC resistance-capacitance step-down solutions, these two chips have stronger load driving capabilities, safer electrical protection and isolation performance! The transformer is also very simple, no need to attach windings, just a single set!
