TIDM-TEMPCOMPENSATED-RTC Microcontroller Based Temperature Compensated Real Time Clock Solution | TI.com
TIDM-TEMPCOMPENSATED-RTC: This report introduced the methodology to implement an ultra low power real time clock with temperature compensation function in MSP430F6736. This report describes the crystal’s temperature characteristics and posts to use MSP430F6736’s RTC_C module plus software to implement a ultra low power RTC, with automatic temperature compensation feature and second ticks generation function. This report finally builds up reference code which runs in MSP430F6736 and provides test result.
TIDA-00434 Cost Effective Bias Power Supply with <100mW Standby and 75% Efficiency Reference Design | TI.com
TIDA-00434: This reference design is a multiple output (12V, 3.3V/5V), 2.4W bias power supply for home appliances using a low cost Quasi-resonant PWM controller. The design supports conversion of wide range DC input ranging from 90V DC to 425V DC or AC input ranging from 85V AC to 300V AC to standard power rails of 12V and 3.3V/5V. TIDA-00434 is able to achieve reduced switching losses, using a buck power stage operating in discontinuous mode with valley switching. The design offers high efficiency (>70%) and low stand-by power of <100mW when system is in idle mode. The design uses low cost external 800V BJT as a switch providing higher operating voltage margin. The PWM controller has integrated safety feature that turns off the external switch in case of loss of feedback which helps in preventing high output voltages. Reconfiguring the designfor different output voltage and standby power consumption levels is easier with simple resistor value changes. Overall the design offers a simple and rugged bias power supply with low standby power.

TIDA-00121 Solar Street Light with Integrated MPPT Charger Reference Design | TI.com
TIDA-00121: This design is a 12A Maximum Power Point Tracking (MPPT) solar charge controller with a 700mA LED driver. It is targeted for low power solar charger and LED driver solutions such as solar street lights. This design is capable of charging 12V batteries with up to 10A output current from 12V panels. However, it can be easily adapted to 24V systems by just changing the MOSFETs to 60V rated parts. Also, the design can drive up to 15 LEDs in series with 700mA of current. It is possible to adapt the design for LED currents up to 1.1A with minimum change in hardware. TI provides a complete solar inverting system for low power loads. Additionally this design takes real world considerations in to account, such as reverse battery protection, built-in battery charge profile for 12V Pb-acid batteries, and a highly efficient design. Together these provide new market entrants and faster time to market for their design.
