The OCP8111A is a current-regulated charge pump LED driver designed for high brightness LED applications, particularly camera flash. It supports both FLASH and TORCH modes, automatically switching between step-up and step-down operations to maintain consistent LED current regardless of forward voltage.
Key electrical specifications include an input voltage range of 2.7V to 5.5V and a maximum output current of 1.0A at 4.2V input. The device operates at a high switching frequency of 1.8MHz, enabling the use of small external components. It features a low shutdown current of less than 1uA and a typical quiescent current of 1.75mA. Protection features include over-current, over-voltage, and over-temperature shutdown.
The OCP8111A is housed in a compact 10-pin DFN package (3mmx3mm) and is specified for operation over an ambient temperature range of -40°C to 85°C. Its design minimizes external components, requiring no inductors, and includes features like automatic soft-start to limit inrush current and PWM dimming control.
This LED driver is suitable for applications such as white LED torch/flash for mobile phones, DSCs, and camcorders, as well as white LED backlighting and general lighting/flash/strobe applications.
