Overview
MIC3201
High Brightness LED Driver with High-Side Current Sense
General Description
Features
The MIC3201 is a hysteretic step-down, constant-current, High-Brightness LED (HB LED) driver capable of driving up to four, 1A LEDs.
It provides an ideal solution for interior/exterior lighting, architectural and ambient lighting, LED bulbs, and other general illumination applications.
The MIC3201 operates with an input voltage range from 6V to 20V.
The hysteretic control gives good supply rejection and fast response during load transients and PWM dimming.
The high-side current sensing and on-chip current sense amplifier delivers LED current with ±5% accuracy.
An external high-side current sense r...
