More stabled white LED lighting can be achieved by direct current connection without electric tolerance and High-speed response by current mode. Moreover, separating IC power supply (2.7V to 5.5V) and coil power supply (2.3V to 20V) makes it possible to widen input range, which will be helpful to be applied to various kinds of applications. Over voltage setting can be selected corresponding to the number of LED lightings. BD60A00NUX is for max 11 lightings, BD60A60NUX is for max 6 lightings. ●Features Boost DC/DC converter Drive LED 11 lightings (VOUT=3.6V×11+0.7V=40.3V <VF MAX=3.7V>) BD60A00NUX Brightness control by outside PWM signal (PWM frequency =100Hz to 30kHz, 25kHz 1% dimming application) Brightness control by DC input Soft start function (1ms Typ.) Over voltage protection BD60A00NUX: 42V (Typ.) BD60A60NUX: 28V (Typ.) SBD open protection and output short protection Over current protection LED terminal over voltage protection UVLO ●Key Specifications Operating power supply voltage range: 2.7V to 5.5V LED maximum current: 30mA (Max.) Switching Frequency: 600kHz(Typ.) Quiescent Current: 0.1μA (Typ.) Operating temperature range: -40˚C to +85˚C ●Package W(Typ.) x D(Typ.) x H(Max.) ●Applications Digital video cameras, digital single-lens reflexes, digital still cameras, digital photo frames, personal navigations (PND), mobile phones, smart phones, MID, PDA, hand-held computers, MP3 players, GPS, digital media players, etc. ●Typical Application Circuit VSON008X2030 2.00mm x 3.00mm x 0.60mm L1 10μH SW EN GND FB VIN Ccoil 4.7μF COUT 2.2μF Coil Power 2.3V to 20V D1 VOUT CIN 1μF 11 LEDs PWM PWM control IC Power 2.7V to 5.5V ISET Enable control BD60AxxNUX |
