Product Description
MP3429 5V 12V Step Up Boost Module Low Ripple 21A Peak Input Current Lithium Battery Booster Power Supply
Module description
This module is a boost switching power supply with high power density. Various voltage outputs (5V, 9V, 12V, 15V) are configured on the board by default, and can be converted to corresponding voltage output only by welding the corresponding jump point. The optimal theoretical conversion rate can reach 97%. It has overheat protection, boost switch enabling pin, regular module layout, layout and wiring in strict accordance with the design specifications of switching power supply circuit, generous materials, small ripple, convenient and practical power output. The MP3429 used in the module is a 600kHz fixed-frequency wide-input range high-integrated boost converter. Starting voltage is as low as 2.7V, single battery power supply can support up to 30W load power, and low on-impedance power MOSFET is integrated. The constant turn-off time control (COT) mode can provide fast transient response. The periodic current protection in the low-end MOSFET can prevent the current from running away, and the high-end MOSFET can avoid using external Schottky diodes.
Precautions for module use
(1) The module has its own enabling function. By default, it is enabled by pulling up. The EN pin can be grounded to disable the module.
(2) If the module heats up in use, the buyer should enhance the heat dissipation according to the actual situation. When the module is loaded with large load, the heat sink can be appropriately increased.
(3) The module is a step-up module, and the input voltage needs to be less than the set output voltage.
