The LUXdrive FlexBlock line of LED drivers are the ideal choice for powering all types of highbrightness and highpower LED packages and arrays. Super Bright LEDs Home: Cart: Menu. A011DVx FlexBlock BuckBoost Driver. A011DVx FlexBlock BuckBoost Driver.Analog Devices buckboost LED drivers allow LED bias when the input voltage is either above or below the LED voltage. This is ideal in cases such as a single cell lithiumion (LiIon) battery driving a single LED where the input voltage can vary from 4. 2 V fully charged down to 2. 7 V fully depleted, while the LED forward voltage can vary from 2 V t buck boost led driver 3adownlow

Abstract: This reference design is for a buckboost LED driver. The MAX currentmode highbrightness LED driver is featured, and the MAX EV (evaluation) kit is used to implement the design. The application note shows the design specifications, schematic, bill of materials (BOM), and performance data. V IN V IN BOOST ENDIM SW FB GND C3 L1 C2 R1 D1 C1 IF ON OFF C4 V OUT The LM3405A is a 1A constant current buck LED driver designed to provide a simple, high efficiency solution for driving high power LEDs. With a 0. 205V resulting in LED drivers that need only a minimum amount of board space. The LM3405A is internally compensated Analog Devices stepup (boost) LED drivers provide current control of multiple LEDs and support for high brightness LED lighting, large format LED backlighting, cameraenabled smart devices, and a range of related applications. Members of this portfolio include I2Ccompatible programming interfaces, with compact, high efficiency features suited to buck boost led driver 3adownlow The device is a buckboost converter which guarantees proper LED current control over all possible battery voltage and LED forward voltage conditions. The output current control ensures good current regulation over the forward voltage spread characteristics of highbrightness LEDs. The STCF07 is a buckboost converter designed to power and control the current of a power white LED. The device operates at a constant switching frequency of 1. 8 MHz (typ). The Buck topology LED driver also has a similar chargedischarge cycle to the buck topology switching power supply. The charge phase of the cycle starts by turning on MOSFET, Q1. This starts an increasing current flow from the battery, through Q1, the inductor, the LED 700 mA1 A Buck Boost LED Driver using FETs, High Side Current Sensing and a NCP3063 Controller Prepared by: DENNIS SOLLEY ON Semiconductor The basic buck boost topology, consisting of a buck and boost converter cascaded together, is illustrated in Figure1.
