OCP8171 Datasheet | ORIENT-CHIP

Description - Features The OCP8171 is a step-up single channel LED - Input Voltage Range : 2.7V to 6V driver with high efficiency DC-DC step-up converter - Drives up to 10 Series White LEDs architecture. With high up to 1.5A current limit allow - High Efficiency PWM Boost Converter OCP8171 to deliver 200m A total current with 10 - 1.2MHz Fixed Switching Frequency strings of 3 WLED in series. Alternatively, OCP8171 - Internal 40V High Current Switch (1.5A Limit) can drive up to 10 white LEDs in series (maximum 36V output) from a single cell Lithium Ion battery. It can also maximize the current capability while M achieve high conversion efficiency. The OCP8171 uses current mode, fixed O frequency of approximately 1.2MHz to reduce the conduction loss and reduce output ripple, improve .C conversion efficiency, and allows for use of small external ponents. The feedback voltage is regulated to 200m V, OCP8171 can also reduce power loss and improves efficiency. P Wide range of PWM dimming through EN pin is I available. The frequency range of the filtered PWM dimming extends up to 200KHz eliminating the H audible noise and suitable for CABC (Content Adaptive Brightness Control) applications. -C The OCP8171 ensures safe operation with plete protection against all fault conditions. Built-in protection circuitry is provided for supply under-voltage, current limiting and over-temperature T conditions. The OCP8171 has integrated a 36V over voltage N protection function through detect the output voltage. When OCP8171 enters the OVP fault status, the E delay timer is active. If the OVP fault status exists I over the delay timer, OCP8171 would be latched to shut-down status. Recovery it from restart the power supply. R The OCP8171 is available in small 6-pin TSOT23 and DFN2020-8L package, OCP8171 is .O rated over the -40°C to 85°C. - Up to 87% Efficiency - Low 200m V Feedback Voltage - Integrated Soft-Start - EN PWM Dimming Range: 20KHz to 200KHz - Small Solution Size -...
