EUTECH  EUP2530OIR1  10 White LED Boost Converter with PWM  MJD Have  in stock 

DESCRIPTION

The EUP2530 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 can be

controlled through the EN pin in two modes. With a

8KHz or higher frequency PWM dimming signal on

EN pin, EUP2530 operates in PWM dimming mode,

which the duty cycle determines the feedback reference

voltage. EUP2530 can operate in digital dimming mode

also, which a Single Wire interface on the EN pin is

integrated to adjust the FB voltage in 32 steps. In either

digital or PWM mode, the EUP2530 does not generate

audible noises on the output capacitor. For the

protection, the EUP2530 provides 41V OVP to prevent

damage from LED open.

The EUP2530 is available in low profile TSOT23-6

package.
