Efficient, Step-down, High-power LED Driver with Strobe and Synchronization for Fire Alarms
PMP9762: This TI Design demonstrates an efficient, step-down, high-power LED driver with strobe & synchronization for fire alarms. A 3-A LED is driven from a common, quasi-regulated 12-V input bus at over 85% efficiency. The circuit supports a clock input for the strobe function, which allows synchronization of multiple LED drivers to a common clock source. As seen at APEC
Isolated Flyback, Bucks (9.6V@0.4A) for Consumer Applications
PMP5539.1: This reference design is a multi-output isolated flyback, working from universal line. The main regulated output is 9.6V; it supplies the main load @ 400mA and two further outputs by means of low power buck converters. The converter takes advantage of the cascode-flyback topology and quasi-resonant working mode to deliver low EMI and good efficiency at light load. A small capacitive coupling circuit sends to the secondary side the information of the mains frequency.
PMP9795 Automotive USB Charging Port Supply Reference Design With Programmable Cable Compensation | TI.com
PMP9795: This reference design includes a power management circuit capable of controlling a remote USB charging port in an automotive application environment. The circuit can be supplied directly from the car battery rail. It uses a small and highly efficient step-down converter, the TPS62130A-Q1, to regulate the required USB bus voltage for charging with charge currents up to 2.5A. The USB charging port is controlled and protected by using a USB charging controller, the TPS2549-Q1, which is also used to monitor the charge current for adjusting the output voltage of the TPS62130A-Q1. This enables the voltage drop across the cable connection to the USB port to be compensated. In addition, the TPS2549-Q1 generates all required signals to indicate a USB charging port to the equipment connected to the port. The required compensation for the voltage drop across the cable connection to USB varies with the cable length. This reference design presets the cable compensation for different cable lengths. It uses a rail-to-rail operational amplifier, OPA348, to adjust the current sinked from the TPS2549-Q1 into the TPS62130-Q1 and set the output voltage of the TPS62130A-Q1 accordingly.
TIDA-00194 Power Regulation & Distribution for Intel SkyLake(TM) Processor Platform Reference Design | TI.com
TIDA-00194: TI's optimized solution for power regulation, distribution, and sequencing for Intel SkyLake™ Processor platform. Utilizing high efficiency DC/DC switching regulators and integrated load switches, this design demonstrates regulation of four unique power rails and distribution of 21 different points-of-load. Significant reduction in board area is accomplished with quad-channel load switches and high-efficiency, integrated DC/DC step-down converters. Furthermore, hybrid I2C/GPIO control reduces or eliminates GPIO requirements, thereby simplifying PCB layout. This design operates with an input voltage range of 4.5V to 15V, simulating 2S/3S Li-Ion battery topologies. A PC-based GUI controls on-board power components over a standard USB cable. Real-time power delivery status feedback is provided via on-board LEDs as well as PC graphics.
