Diodes Incorporated AL3157F-7 is a highly integrated 4-output LED driver IC featuring a switched capacitor (charge pump) topology. This device is designed for applications requiring efficient DC-DC regulation and precise brightness control. The AL3157F-7 supports PWM dimming for granular control over LED intensity, offering output currents up to 30mA and 210mA per channel. Its internal switching capabilities and a 1.2MHz operating frequency contribute to a compact solution. The device is packaged in a 12-UFDFN exposed pad (U-DFN3030-12) for surface mounting, suitable for space-constrained designs. Operating within a supply voltage range of 2.7V to 5.5V, it is specified for operation across an ambient temperature range of -40°C to 85°C. This component is commonly utilized in backlight applications.
