DD0503MA Ultra Mini DC 3.7V to 4.5V DC-DC Step Down Converter Buck Module https://bit.ly/2G5QQNm Perfect for use with 18650 batteries (3.7V to 4.2V) or another 3.7V to 6V power source. It will step down the voltage from 4.5V to 3.3V for 3.3V devices such as 3.3V microcontrollers or other 3.3V IoT devices. Description: Input voltage 3.3-6V, output 3.3V (deviation +/– 4%) Long time maximum output current 500mA Short time maximum output current 700mA Conversion efficiency: 81-93% The maximum input voltage cannot exceed 6.5V INPUT 3.7V/600MA; OUTPUT 3.3V/540MA INPUT 4V/600MA; OUTPUT 3.3V/610MA INPUT 4.2V/580MA; OUTPUT 3.3V/600MA INPUT 4.5V/550MA; OUTPUT 3.3V/610MA INPUT 5V/470MA; OUTPUT 3.3V/590MA INPUT 6V/370MA; OUTPUT 3.3V/550MA DC-DC Buck Step-down module working frequency 1.2MHZ. Operating ambient temperature: -40~+85 Degrees Celsius 2.54mm pin pitch, Arduino Uno Due Breadboard FPGA/CPLD Development Board friendly. Excluding Pin Size 10.8mm x 7.7mm x 5.6mm (Very small) Weight: <1g (Very light) Applications: Wifi Module: ESP8266 Bluetooth module: HC-05 HC-06 Wireless UART module: HC-11 HC-12 wireless module: CC2500 SI4432 SI4463 CC1101 CC2500 Nrf24l01+ 3-3.5V LED lights 3.3V Development Board: ARM STM32 FPGA/CPLD MSP430 Attention: This is a DC-DC voltage converter module, Must be noted when using: 1 Input voltage cannot be greater than the maximum input range. 2 Output power cannot be greater than the maximum load for a long time. 3 Input power must be greater than the output power because the power consumption of the module itself.
