LM2577 DC-DC Step Up Module

Product Features:

The module uses high-quality LM2577 chips, with high efficiency (92% higher) and low heat generation. It can reach up to 15W without the addition of a heat sink, and can reach an output power of 20W with the addition of a heat sink

This module uses original Sanyo filter capacitors with low ESR, and in order to reduce the output ripple, an additional LC filter circuit is specially added at the output end, which can reduce the ripple voltage to 50mV (in the case of 24V output voltage, 12V is below 20mV), suitable for most occasions.

This module uses machine mounting and reflow soldering. At the same time, each module has undergone two hours of aging test before shipment to ensure high reliability.

Note: When you test, if the output voltage is not higher than the input voltage, please adjust the potentiometer clockwise, the output voltage will rise, please do not adjust counterclockwise, so that the module will be damaged under high input voltage!

Product Parameters:

● Efficiency=14.2 × 0.6/6 × 1.653=86%

● New version of high-power boost dc-dc

● The input current is 3A, and the rated working voltage is recommended to be within 2A.

● Appearance dimensions: L * W * H 4.3cm * 3.0cm * 1.2cm

● About 85% efficiency

● Adjustable high-efficiency boost circuit DC-DC booster, with an input voltage of (3.7 to 30) V, an output adjustable of (4 to 30) V, an input current of 3A, and an efficiency of up to 92%. It is easy to use as a commonly used single lithium battery with a 3.7-liter 5V for mobile charging banks. The 3A driving current can charge multiple mobile phones, MP4, and other devices at the same time without any problem. The use of a dedicated large packaged boost chip LM2577 is not within the reach of a mung bean sized boost IC, and the output driving power can reach up to 20W

Typical Applications:

1. 3.7 to 5V for mobile power bank

2. Boost drive LED light string (suitable current limiting resistor needs to be added)

3. 7.4V boost 12V application in aircraft model camera

Attention: When working with high current, a large amount of heat will be generated. Please pay attention to strengthening ventilation and heat dissipation.
