      MP2307 3A / 23V 340KHz Synchronous Rectifier Buck Converter 3.3V Adjustable Winder

       

      The MP2307 is a monolithic synchronous buck regulator. The device integrates 100mΩ MOSFETS that provide 3A of continuous load current over a wide operating input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on and in shutdown mode, the supply current drops below 1µA. This device, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components.

  • Voltage regulator 3.3V HT7333-A 7333-A HT7333 HT7333A-1 TO92 Low Consumption LDO New Original ()
    The HT73xx-7 is a low power high voltage series of regulators implemented in CMOS technology which has the advantages of low voltage drop and low quiescent current. They allow input voltages as high as 30V and are available with several fixed output voltages ranging from 2.1V to 5.0V. When the CE input is low, a fast discharge path pulls the output voltage low via an internal pull-down resistor. An internal over-current protection circuit prevents the device from damage even if the output is shorted to ground. An over-temperature protection circuit ensures the device junction temperature will not exceed a temperature of 150°C.

  • New Led Ring 16x 5050 RGB LED Board with Integrated Drivers Module Geekcreit for Arduino - products that work with official Arduino boards ()
    16 ultra bright smart LED are arranged in a circle with 1.75" (44.5mm) outer diameter. 
    The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! 
    Each LED is addressable as the driver chip is inside the LED. 
    Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. 
    Power the whole thing with 5VDC (4-7V works) and you're ready to rock.
    There is a single data line with a very timing-specific protocol. 
    Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, , PIC, mbed, etc. 
    It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. 
    As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. 
    An 8MHz or faster processor is required.
    Comes as a single ring with 16 individually addressable RGB LEDs assembled and tested.
