MAX16819 Datasheet | Maxim Integrated

Description The MAX16819/MAX16820, step-down constantcurrent high-brightness LED (HB LED) drivers provide a cost-effective solution for 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/10m A 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 applications requiring a wide input voltage range. The high-side current-sensing and an integrated current-setting circuitry minimize the number of external ponents while delivering an LED current with ±5% accuracy. A hysteretic control algorithm ensures excellent input-supply rejection and fast response during load transients and PWM...
