Solved by SP7619/19A Constant Current LED Driver FEATURES • Very low dropout voltage • Accurate current regulation down to dropout voltage • No external components • Selectable output current levels 200mA & 500mA 700mA for SP7619A • Power-saving shutdown mode of 1µA • Fast turn-on <50µs • Timeout function to protect the LED • Thermal Shutdown protection • RoHS compliant, Lead Free packaging: Space saving 2mmx3mm 8pin DFN LED 1 LED 2 VCC 3 EN 4 SP7619 8 Pin DFN 8 GNDP 7 GNDP 6 GND 5 CTRL APPLICATIONS • Next Generation Mobile Phones • PDA, DSC, MP3 Players • Handheld Computers • LCD Display Modules GENERAL DESCRIPTION The SP7619 is a linear low-side, constant-current driver designed to drive high power LEDs from an input voltage rail. The driver acts as a current source, ensuring constant LED current across a range of input voltages. The SP7619 allows implementing the lowest cost LED driver for a variety of applications. Internal circuitry maintains the preset constant current output for a wide voltage range at the LED input. The LED current can be set at 200mA at torch mode or 500mA 700mA SP7619A at flash mode by selecting CTRL pin low/high respectively. Dimming or shutdown can be done by feeding a PWM signal to the EN pin. Fast EN turn-on/off time allows for very fast dimming frequencies, completely eliminating flicker. The built-in thermal protection automatically stops LED current to prevent overheating. A timeout function serves as a fail safe, shutting down the output at 500mA 700mA current after 4 seconds of continuous operation if the enable input is not cycled. The Enable pin should be cycled HIGH/LOW/HIGH to restart the driver.
