3.7V 5V 6V 9V 12V to +15V/-15V DC DC Converter Step up Boost Dual Voltage Power
Product Name: 3.7V 5V 6V 9V 12V to +15V/-15V DC DC Converter Step up Boost Dual Voltage Power supply Packing list: 1 PCS 3.3V-13V TO ±15V Dual voltage DC DC Boost Converter Module Description: Input voltage DC 3.3 ~ 13V,output DC ±15V(Deviation is ±4%) Maximum input current 1.8A Maximum output current : +Vo is 600A,-Vo is 120mA Quiescent current: 3-4mA DC DC Boost Converter Module working frequency 400kHz. Operating temperature range : -40~+125 Degrees Celsius Storage temperature range : -65~+150 Degrees Celsius 2.54mm pin pitch,for MCU Development Board Breadboard friendly. Size : 25 x 16.3 x 6.6mm Weight :3g Internal Optimize Power MOSFET High efficiency up to 90% Built in Frequency Compensation Built in Soft-Start Function Built in Thermal Shutdown Function Built in Current Limit Function Note: 1 Due to the diode partial pressure, the voltage of -Vo is lower than +Vo 2 In order to obtain a more stable voltage, it is recommended that the output is greater than 1MA 3 -Vo cannot be used alone, or no voltage output.But you can just use +Vo Applications ADC/DAC/Operational Amplifier RS232 RS485 RS422 Bus Audio equipment LCD power supply Instrumentation equipment ARM MCU FPGA/CPLD Board Analog acquisition Power amplifier/Speakers multimeter Attention : This is a DC-DC voltage converter module,Must be noted when using: 1 Input voltage can not be greater than the maximum input range 2 Output power can not 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 Q & A: Q : Why output voltage is less than the nominal voltage A : Input power supply power is too low.Test the input voltage with a multimeter,a t this time of the input voltage is very low
5Pcs DC 3.3V 3.7V 5V LED Driver 30-1500MA Constant Current Adjustable Module PWM
The frequency of the PWM signal should be less than 2KHz. 30-1500MA LED Driver Constant current adjustable Module( no Pin). The on-chip power transistor and current sense block greatly reduce the external component count, which makes the LD06AJSA/B ideal for LED driver.
