High-Voltage Inductorless Regulated 4-Channel LED Driver

The ZD3315 contains 4 channels of linear regulated, low drop out current sources, speci cally designed to drive up to 4 strings of LEDs with 150mA sourcing current per chan- nel. Each LED string operates individually by terminating to an internal, regulated current sink, which provides matched and consistent LED current over a wide input supply range. The LED currents are set by an external resistor, RSET, connected to the ISET pin. The EN pin provides a chip en- able function and CAN be used with a PWM pulse to achieve a dimming control function. Dimming CAN also be achieved by applying a DC voltage through the RSET or a resistor network at the ISET pin. By ywyn Corporation
