EUP2537
bkf 10 White LED Boost Converter with PWM Dimming
DESCRIPTION
The EUP2537 is a constant current step-up converter specifically designed to drive white LEDs.
With a 45V rated integrated switch FET, the step-up converter supports up to 10 white LEDs in series connection, so the LED currents are identical for uniform brightness.
The boost converter runs at 1.
0MHz fixed switching frequency with 1.
3A switch current limit, and allows for the use of a high brightness LED in general lighting.
The maximum white LED current is set with the external sensor resistor RFB, and the feedback
voltage is regulated to 200mV, as shown in the typical application.
During the operation, the LED current c...
