   Product Features

The module uses high-quality LM2587 chip, with an instantaneous input current of up to 5A, high efficiency (92 PERCENT), low heat generation, and can reach 15W without adding a heat sink. After adding a heat sink, the output power can reach 20W.

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

This module uses machine mounting and reflow soldering, and each module undergoes a two-hour aging test before shipment to ensure reliability.

   Product Applications

★ DIY a portable power bank that only requires a single lithium battery to power the input, and can output a voltage of 4-35V to power many devices such as your phone, MP3, MP4, PSP charging, etc. It's very simple and convenient.

★ Boost charger, you can charge your 4-35V device with 2 AA batteries or lithium batteries.

★ To power your electronic devices, when your device requires 4-35V power supply, but you currently only have a lithium battery for power supply, our module can directly boost it to 4-35V, solving your problem.

★ System front-end power supply. When you input a power supply voltage lower than the voltage you need (4-35V) when working on a project, choosing our module will be a good choice. You can work directly on the machine without debugging, easily achieving efficient and high-power boosting.

   Product Precautions

This module is an adjustable boost module that can change the output voltage by adjusting the blue adjustable resistor on top of the module. The maximum output voltage is 35V.

The IN - (input negative), IN+(input positive), OUT - (output negative), and OUT+(output positive) marked on the module must be connected correctly, otherwise it may cause damage to the module.

Do not exceed the rated output power of this module, for example, this module (20W) cannot be used to supply laptops (90W).

This module does not have output short circuit protection. If the output short circuit persists for a long time, it may cause damage to the module.
