Mini 3A DC-DC Converter Step Down Module

Original price was: ₹167.00.Current price is: ₹72.00. (Excluding 18% GST)

TheĀ Mini 3A DC-DC Converter Step Down ModuleĀ is a compact voltage regulator designed to convert higher input voltages to lower output voltages. Here are some key details about this module:

  1. MP2307-Based Design:
    • The module is based on theĀ Monolithic Power Solutions MP2307Ā chip, which is aĀ 3A, 23V, 340kHz synchronous rectified step-down converter IC.
    • It features an integrated MOSFET capable of providingĀ 3A continuous outputĀ over an input voltage range ofĀ 4.75V to 23V.
    • The chip offersĀ cycle-by-cycle overcurrent protectionĀ andĀ under-voltage lock-out.
  2. Specifications:
    • Input Voltage Range: 4.75V to 23V.
    • Output Voltage Range: 0.925V to 20V (adjustable via a trimpot).
    • Maximum Current: Up toĀ 3AĀ (although some listings mention 1.8A continuous).
    • Efficiency: Up toĀ 96%Ā conversion efficiency.
    • Size: Tiny, about the size of two thumbnails.
    • Output Ripple: Typically less thanĀ 30mV.
    • Switching Frequency: AroundĀ 1.5 MHzĀ (highest), usuallyĀ 1 MHz1.
  3. Usage:
    • Connect your input voltage (up to 23V) to the moduleā€™s input pads.
    • Adjust the output voltage using the small trimpot.
    • Itā€™s suitable for compact projects due to its small profile.

Keep in mind that this module lacks reverse polarity protection, so ensure correct wiring.
