DC-DC Boost/buck Converter DC1.8-5.5V to 3.3V4.2V5V3A Adjustable Output Low Ripple Mini Constant Voltage Board Module

Features:1.Provide 3.3V/4.2V/5V commonly used output voltage customers can freely adjust the2. High-performance circuit design to reduce energy loss and ensure stable and reliable output.3. Small size, light weight, easy to embed in a variety of equipment or DIY projects4. Built-in multiple protection mechanisms to ensure the safe operation of the module and the connected equipment.5. Selection of high-quality materials, product quality is guaranteed, performance is more stable.Parameter:Input voltage: DC1.8V-5.5V (recommended 2V or more)Output voltage: 3.3V/4.2V/5V (short-circuit regulation)Maximum operating current: 3ARegular / power saving mode optionalOutput short circuit protectionBuilt-in over-temperature protectionProduct Description: the use of original imported big brand chip, the maximum operating current of 3A, the actual situation according to the pressure difference and heating conditions reasonable choice, low power consumption can be used to short ps set point-saving mode, and remove the LEDs to reduce static power consumption, the output voltage can be set by shorting the point, and set aside a resistor welded position in order to set the other voltageWiring instructions:VIN: DC input positive 1.8V-5.5VGND: DC input negative terminal, connected to output negative terminalOUT: DC output positivePS short point: shorted from the regular module into the power saving modeEN: module work enable, low level off the default output workAttention:1. Input and output maximum 3A (the output does not exceed 3A in buck, and the input does not exceed 3A in boost). The actual current depends on the pressure difference and heat dissipation.2. Without reverse connection protection, the module works with a min voltage of up to 1.8V, but the output power is small at low voltage.3. The wiring can not be too thin, to ensure that the wire can withstand the corresponding current4. Inductive loads to do a good job of protection, to avoid excessive reverse electromotive force beyond the chip's tolerance range5. The more power the module uses, the closer the current is to the maximum current. The greater the heat will be, pay attention to the use of heat dissipation6. Module in conventional mode with different voltage output and input standby current of a few ma to dozen ma are normal, short PS, remove the LED lights, standby can be done within 100uA7. User-defined output voltage, short 3V3 pad output 3.3V voltage, the same 4V2 pad output 4.2V, prohibit simultaneous shorting of multiple padsPackage include:Lift-off module *1
