Overview
IZ1937 White LED Step-Up Converter (Functional equvalent of LT1937 Linear Technology Corporation) Description The IZ1937 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current.
The device can drive two, three or four LEDs in series from a Li-Ion battery.
Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.
The IZ1937 operates at 1.
2MHz, allowing the use of tiny external components.
The output capacitor can be as small as 0.
22uF, saving space and cost versus alternative solutions.
A low 95mV feedback voltage minimizes power loss in the current setting resistor for b...
