  LT1937 switching inductive boost converter chip power switch voltage values up to 36V, can   LED Bulb  drive six white LED in series consisting of single load. Sampling resistor voltage drop of about 100mV, by adjusting the sampling resistor sets the output current is set to 5 ~ 20mA. White LED brightness adjustment can still be used to introduce additional nodes in the feedback control current pulse width modulated signal can be fed into the control terminal off the two methods.

LED Module

    Belonging inductive boost switching converter device also LM2704 and LX1993, LM2704 can be 2.2 ~ 7V voltage range, the maximum output voltage of 20V, the output current is 20mA, capable of driving two totaling eight white LED.

  LED Flexi Strip

 LM2704 is characterized by on-chip power switch peak current up to 0.5A, on-resistance of only 0.7Ω, and therefore a higher power conversion efficiency, and easy to solve the problem of heat dissipation small package devices. LX1993 able to 20mA output current drive single four white LED, the advantage of the supply voltage as low as 1.6V.
