Detailed Product Description
Product Details
DESCRIPTIONThe LT®3495/LT3495B/LT3495-1/LT3495B-1 are low noise boost converters with integrated power switch, feedback resistor and output disconnect circuitry. The parts control power delivery by varying both the peak inductor current and switch off-time. This novel* control scheme results in low output voltage ripple as well as high efficiency over a wide load range. For the LT3495/LT3495-1, the off-time of the switch is not allowed to exceed a fixed level, guaranteeing the switching frequency stays above the audio band for the entire load range.
FEATURES■ Low Quiescent Current60µA in Active Mode 0.1µA in Shutdown Mode ■ Low Noise Control Scheme (Switching Frequency Always Stays Above Audible Range for LT3495/-1) ■ Integrated Power NPN: 650mA Current Limit (LT3495/B) 350mA Current Limit (LT3495-1/B-1) ■ Integrated Output Disconnect ■ Integrated Output Dimming ■ Wide input range: 2.5V to 16V ■ Wide output range: Up to 40V ■ Integrated feedback resistor ■ Tiny 10-Lead 3mm × 2mm DFN Package
APPLICATIONS■ OLED Power■ Low Noise Power ■ MP3 Player
