Negative voltage generation polarity reversal negative 5V power supply negative voltage module far exceeding icl7660-5v9 (h3a6)MVI-01 negative voltage/polarity reversal module
I. Module function:The Polar Flip module is used to convert the positive voltage to the same negative voltage. It can provide negative power supply and negative pressure reference for operation and release.Input positive voltage, output negative voltage. The input voltage is much larger than the output voltage.
II. the characteristics of the module:1. Maximum current 200mA, can support a number of negative power supply, negative pressure reference and so on, easy to deal with!2. Ripple Low to 15mv!!! (50mA output), rated output ripple 90mv (200mA output)3. Maximum efficiency of 99% (50mA output), rated output efficiency 91% (200mA output)4. Charge pump mode, the circuit concise and stable, high reliability should be used in industrial occasions!5. PIN installation, 2.54m standard spacing 3P, (also can adapt to 2.0 of the hole distance), convenient directly integrated into the circuit board.5. Ultra Small size: does not contain the pin size 10mmx20mmx3mm.
III. Model Description1, MVI-01 200mA, red PCBRated current 200mA (actual Max to 300mA), input voltage 1.5-5.5v. With frequency selection and low voltage input selection.Features: low voltage, large current. Main PUSH model!
IV. PIN definition+: Positive voltage input EndV: Negative voltage output endGND: power source.FC Flag: Frequency selection end, short-circuit 150KHZ, disconnect 20khz,200ma model default is short (20mA model default).Modify the vibration frequency can be targeted to reduce the interference of the circuit!LV Logo: Low voltage selection end, for MVI-01 2662 and MVI-01 7660 input voltage less than 3.5V short-circuit, can improve low-voltage output performance. Default fracture.
