Part Details for CSD17573Q5B by Honest Han

This reference design is a 650-W inverter power stage designed for low-frequency (transformer-based): single-phase UPS operating from a 12-V battery. The design enables low form factor and high-efficiency implementation: taking advantage of the TI SMD MOSFET in a SON5x6 package with very low RDS(on) and low gate charge (Qg). Using two devices in parallel for each leg of the full-bridge power stage: the power stage eliminates the need of a heat sink: which reduces overall system cost.

This design is a non-synchronous buck converter which operates at 5.0V input voltage and provides 1.3V @ 600mA. For comparisson of the size of the passive components and the performance, one converter is running at 1.6 MHz, the other one at 3.0 MHz.

The TIDA-00735 reference design is a 10.8V to 25.2V brushless DC motor controller for high power propeller: fan: and pump applications. It uses the Texas Instruments' DRV8303 brushless DC motor gate driver: CSD17573Q5B 30V NexFET™ power MOSFETs: MSP430 16-bit low power MCU: and TPS70933 30V ultra-low IQ LDO. It controls motor with trapezoidal sensor-less control algorithm and commands the motor speed through an external reference signal from a central controller. This design is focused on demonstrating a highly efficient and high power BLDC motor system.

PMP10709 is a system optimized 50 W power designs for A13 Wireless Charger Transmitter used in automotive system. The design has various front end automotive protections such as Load dump through TVS (ISO pulse testing): Reverse Voltage (Through PFET’s body diode): Battery Disconnect Switch with OVP protection (PFET). PMP10709 is primarily four Switch synchronous Buck – Boost design: which supports wide Input voltage range (7V-20V) and delivers any output from 1V-10V based on DAC output of the A13 Wireless Charger. The DAC output changes from 1V to 3.3V which in turn changes the output voltage from 10V to 1V (on the fly) as needed by the algorithm of A13 wireless charger’s transmitter. This design utilizes best in Class Synchronous four Switch Buck Boost Controller LM5175. The design accepts an input voltage of 7Vin to 20Vin and provides the output of 1V- 10V@5 A. Output current never exceeds 5A to protect the charging Coil. The average current regulation loop of the IC at the output is used for this protection.
