General Description
The MIC3203 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 MIC3203 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 current sense resistor is used to set the output current.
The MIC3203 offers a dedicated PWM input (DIM) which enables a wide range of
pulsed dimming. A high-frequency switching operation up to 1.5MHz allows the
use of smaller external components minimizing space and cost. The MIC3203
offers frequency dither feature for EMI control.
The MIC3203 operates over a junction temperature from −40°C to +125°C and is
available in an 8-pin SOIC package.
A dither disabled version MIC3203-1 is also available in the same package as
the MIC3203.
