com YB1522 Step-up DC-DC Converter White LED Driver Features „ Built-in Internal Switch „ 3V to 16V Input Range „ <1uA Shutdown Current „ High Efficiency „ Internal Soft Start „ Drives up to 3S7P to 3S10P White „ „ „ „ Description The YB1522 is a step-up DC-DC converter; with wide input voltage range from 3V to 16V, which operates as current source to drive up to 3S7P to 3S10P (VIN at 3V to 5V).
Series connecting of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.
The light intensity of these LEDs is proportional to the current passing through them.
The YB1522 switches at a fixed frequency of ~930KHz, a...
