MIC3202/MIC3202-1
High-Brightness LED Driver with Integrated MOSFET and High-Side
Current Sense
General Description
Features
The MIC3202 is a hysteretic, step-down, constant-current, High-Brightness LED (HB LED) driver. It provides an ideal solution for interior/exterior lighting, architectural and ambient lighting, LED bulbs, and other general illumination applications.
The MIC3202 is well suited for lighting applications requiring a wide-input voltage range. 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 currentsense resistor is used to set the output current.
