Demonstration circuit 871 is a low noise high current LED charge pump featuring the LTC®3215 and a cell phone camera flash LED. The board has three versions (-A, -B, -C) that are optimized separately for a short LED flash current or a lower but constant LED torch current with a single lithium ion battery input voltage range of 2.9V to 4.4V or three AAA batteries in series. The lithium ion battery…

The MAX16820 evaluation kit (EV kit) demonstrates a step-down, constant-current, hysteretic controlled switching regulator for driving high-brightness LEDs (HB LEDs) using the MAX16820 controller IC. This EV kit is configured to supply an average output LED current of 1A, and operates from a 5V to 28V supply.

The AL5812 is an adjustable Linear LED driver offering excellent temperature stability and output handling capability. The AL5812 simplifies the design of linear and isolated or non-isolated LED drivers by setting the LED current with standard value resistors.

The MIC2287 is a small 1.2 MHz constant frequency PWM white LED driver. The MIC2287 is available in either a thin SOT-23 or a 2 mm x 2 mm MLF™ package. High power densities in a very small size are achieved using its internal 34 V/500 mA switch.

The A6211 is a single IC switching regulator that provides constant-current output to drive high-power LEDs. It integrates a high-side N-channel DMOS switch for DC-to-DC step- down (buck) conversion. The A6211 EVB (evaluation board) accepts input voltage from 6V to 48V to drive a single LED string. LED current can be from several hundred mA up to 3A, selected by jumper combination on the EVB. Swi…
