2MHz High-Brightness LED Drivers with
High-Side Current Sense and 5000:1 Dimming
General Description
Features
The MAX16819/MAX16820, step-down constant-current
high-brightness LED (HB LED) drivers provide a cost-
effective solution for automotive interior/exterior lighting,
architectural and ambient lighting, LED bulbs such as
MR16 and other LED illumination applications.
The MAX16819/MAX16820 operate from a 4.5V to 28V
input voltage range and feature a 5V/10mA on-board
regulator. A high-side current-sense resistor adjusts the
output current and a dedicated PWM input (DIM)
enables a wide range of pulsed dimming.
The MAX16819/MAX16820 are well suited for applica-
tions requiring a wide input voltage range. The high-side
current-sensing and an integrated current-setting circuit-
ry minimize the number of external components while
delivering an LED current with ±5% accuracy. A hys-
teretic control algorithm ensures excellent input-supply
rejection and fast response during load transients and
PWM dimming. The MAX16819 features a 30% inductor
