CN5820 Datasheet | CONSONANCE

Description ： The CN5820 is a switch-mode step-down constant-current high-brightness LED (HB LED) driver, the device provides a cost effective solution for automotive interior/exterior lighting, architectural and ambient lighting, LED bulbs such as MR16 and other LED illumination applications. The CN5820 operates from a 4V to 28V input voltage range and features a 5V/5m A on-board regulator. A high-side current-sense resistor adjusts the LED current and a dedicated input (DIM) enables PWM dimming and analog dimming. The CN5820 is 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 dimming. The CN5820 features a 20%...
