General Description
The MAQ3203 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 MAQ3203 is well suited for lighting applications
that require 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
comparator delivers LED current with ±5% accuracy.
An external high-side current-sense resistor is used to
set the output current.
The MAQ3203 offers a dedicated PWM input (DIM)
that 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 MAQ3203 offers
frequency dither feature for EMI control.
The MAQ3203 operates over a junction temperature
from –40°C to +125°C and is available in an 8-pin SOIC
package. The MAQ3203 is AEC-Q100 qualified for
automotive applications.
