Welcome to my ebay store! You will find your favorite products. Pass by do not miss.thank you! Product Detail ( ---☆ ayanhu81 ebay shop welcome you to buy it ☆---) Module description: Polarity inversion module for converting a positive voltage into a negative voltage of the same. To provide for the op amp negative supply and negative reference. Positive input voltage, output voltage is negative. How much input voltage output voltage is how much. Module features: 1. Maximum current 200mA, can support multiple op amp negative supply, negative reference and so on, easy to deal with! 2. Ripple low as 15mv !!! (50mA output), the rated output ripple 90mv (200mA output) 3. The maximum efficiency of 99% (50mA output), rated output efficiency of 91% (200mA output) 4. The charge pump circuit is simple and stable, high reliability used in industrial applications! 5. Install pin, 2.54m standard pitch 3P, (also can be adapted to 2.0 pitch) to facilitate integrated directly into the circuit board. 6. The ultra-small size: free pin size 10mm × 20mm × 3mm. Model description: Rated current 200mA (actual maximum to 300mA), the input voltage 1.5-5.5V. And the low-band frequency selection input selection. Features: Low voltage, high current. The main push model! Highly recommended! Pin definitions: V +: Positive voltage input V-: Negative voltage output GND: power ground. FC sign: frequency selection terminal, short circuit 150KHZ, disconnect 20KHZ, 200mA default models are shorted. Modify the oscillation frequency can be targeted to reduce interference to the circuit! LV logo: Choose low-voltage side, the input voltage is less than 3.5V short circuit, low voltage output can improve performance. Default disconnected. Caution! 1. The charge pump is a non-resistive voltage output, as the output current increases, the voltage will gradually decline, which is a normal phenomenon, please be sure knows! 2. Do not reverse the polarity of the input and output, as this may damage the module! 3. Do not exceed the input voltage limit. Or it may burn. MVI-01 200mA typical test values: 1. Efficiency: 91% -99% (output 50mA 99%, at 100mA 96%, at 200mA 91%) 2. Output voltage drop: (drop output 50mA 0.1V, 100mA when the voltage drop 0.2V, 200mA at 0.45V) 0-0.45V 3. Ripple: 5-90mv (50mA output ripple of 15mv, 100mA Ripple 60mv, 200mA Ripple 90mv) ( ---☆ ayanhu81 ebay shop welcome you to buy it ☆---) Package included: 1x LM2662 Negative Voltage Converter Module Feedback > We maintain hightest buyer ratings > Positive Feedback will be much appreciated from you. > Any dissatisfaction, please contact us immediately! > Please do not leave neutral or negative feedback before we help you out.
