The MAX16819/MAX16820 operate over the -40☌ to +125☌ automotive temperature range and are available in 3mm x 3mm x 0.8mm, 6-pin TDFN packages. These devices operate up to 2MHz switching frequency, thus allowing for small component size. The MAX16819 features a 30% inductor current ripple and the MAX16820 features a 10% current ripple. converter is controlled to give controlled LED current. A hysteretic control algorithm ensures excellent input-supply rejection and fast response during load transients and PWM dimming. The MAX16813B high-efficiency, high-brightness LED (HB LED) driver provides four integrated LED current-sink channels. a high brightness, high efficiency, dimmable LED driver based. Regulated LED Current Linear or PWM Brightness Control Inputs. The high-side current-sensing and an integrated current-setting circuitry minimize the number of external components while delivering an LED current with ±5% accuracy. MXHV9910 is a low-cost, high-brightness (HB) LED driver that operates from a universal AC. The MAX16819/MAX16820 are well suited for applications requiring a wide input voltage range. 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 operate from a 4.5V to 28V input voltage range and feature a 5V/10mA on-board regulator. Dim to Warm functionality provides for accurate control of the correlated color temperature (CCT) of a two-channel dimmed LED light source from full brightness. Power factor greater than 0.The MAX16819/MAX16820, step-down constant-current 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.No-load power consumption less than 100mW.The RT9288A is a wide input operating voltage range step up controller.
