50W dual-stage LED driver reference design with adaptive pre-boost control for automotive headlights

The TIDA-01520 two-stage reference design drives two LED strings in automotive headlight applications and automatically adjusts the pre-boost voltage without the need for a microcontroller (MCU), saving space and cost. In addition, the design's adaptive pre-boost control feature reduces switching losses and maximizes system efficiency for automotive headlights.

SensorTag TI Design

The new SimpleLink™ multi-standard SensorTag kit helps you realize your Internet of Things (IoT) product ideas. The kit contains 10 low-power MEMS sensors in tiny packages that are expandable using DevPacks, making it easy to add your sensors or actuators. Connect to the cloud via Bluetooth® and get sensor data online in three minutes. SensorTag works right out of the box with iOS and Android apps, so no programming experience is required to get started. The new SensorTag is based on the CC2650 wireless microcontroller (MCU) and consumes 75% less power than previous Bluetooth products. Therefore, the SensorTag kit can be battery powered and a coin cell battery will last for many years. Bluetooth SensorTag contains iBeacon technology. As a result, your phone can launch apps and customize content based on SensorTag data and physical location. Additionally, SensorTag kits are enabled via ZigBee® and 6LoWPAN technologies.

AM437x low power suspend mode using LPDDR2

This low-power mode scheme achieves processor power consumption of less than 0.1 mW while maintaining LPDDR2 memory power consumption in the self-refresh state at approximately 1.6 mW. The system solution consists of AM437x Sitara processor, LPDDR2 memory and TPS65218 power management IC, and has been optimized for new low-power modes while supporting traditional low-power modes. Minimize processor power by turning off all processor power except the RTC power. System power state transitions, including power control, can be performed by a single interface signal (PMIC_PWR_EN signal) using PMIC register programming.
