Product features:
★ This model is made using an imported main control chip, which is fixed at a 1.2MHz oscillation frequency. The internal MOSFET uses an ultra-low on resistance (Ron), ensuring stable and efficient overall operation.
This module has over temperature protection and over current protection functions, which can ensure the safety of electrical appliances and modules.
★ This module has an ultra small volume, only 20 * 20 * 5 (length, width, height), and weighs less than 10 grams. It is very suitable for high current and small volume applications, such as aviation models.
This module uses machine SMT and reflow soldering, and each module undergoes two hours of aging testing before shipment to ensure high reliability.
