| .COM LX1995 Miniature LED Driver PRODUCTION DATA SHEET KEY FEATURES The Microsemi LX1995-x is a The LX1995-x output current is < 1µA Shutdown Current miniature LED driver with integrated programmable using an external current > 85% Maximum Efficiency drivers. It is designed to drive white sense resistor in series with LEDs. This or color LEDs in portable display configuration provides a feedback to the Efficient at Low Current Levels < 70µA Quiescent Supply applications. The LX1995-x is an FB pin which maintains constant output adjustable step-up boost converter. current independent of input voltage The LX1995-x can switch up to 2MHz and LED forward voltage VF . LED allowing designers to use a low cost, dimming is accomplished using a PWM small inductor and filter capacitor. signal or varying DC voltage methods. The driver supports a wide input The LX1995-x is available in the 5voltage range 1.6V to 5.5V with Pin TSOT and SOT-23 package. The efficiency greater than 85% and can LX1995-1 can drive up to 6 LEDs e start up at 1.6V input. The LX1995-x switching current is 325mA . The is a low cost, high efficiency LED LX1995-2 can drive up to 10 LEDs driver. The design is based on a switching current is 500mA . t pseudo-hysteretic pulse frequency modulation topology. In portable battery applications the LX1995-x offers high system efficiency with low le quiescent current in operation IQ is < 70µA and in standby IQ is < 1µA.
