EUP2983 White LED Driver For Buck-Boost Application DESCRIPTION The EUP2983 is a constant current boost converter specially designed for driving white LEDs with wide input range. The unique converter topology provide a load voltage which can be greater or less than the input voltage. With the tightly regulated load current, the EUP2983 allows series connection with multiple strings of the white LEDs. The brightness of the LEDs can be adjusted through a voltage level on the CTRL pin or by applying a PWM signal to CTRL pin. 1MHz current-mode, pulse-width modulated (PWM) operation allows for small input and output capacitors and a small inductor while minimizing ripple on the input supply/battery. Programmable soft-start eliminates inrush current during startup.
