MAX16819/MAX16820
The MAX16819/MAX16820 are buck-mode HB LED drivers featuring
an external switching MOSFET for applications with more than 1A
current. They provide hysteretic control of the LED current so that
they do not need a compensation circuit. They require very few
external components, are low in cost, and are available in a small
package size (3mm x 3mm). These are dependable products for the
harsh operating environment of industrial applications.
