CSD17308Q3

The PMP5322 reference design provides and isolated 14V at 4.7A from a universal AC input. The UCC28600 flyback controller used in this design reduces standby power consumption to less than 200mW by operating in burst mode at light loads, and provides efficiency over 87% at heavier loads by reducing switching losses through quasi-resonant valley switching.

This reference design generates a 0.9V/7.5A output from a 12V input using the TPS40192 synchronous buck controller. The low Rds and fast switching of the CSD17313Q2 and CSD17308Q3 provide over 83% efficiency.

This reference design is for USB Power Delivery (PD) battery charging applications: such as power banks or other portable devices. It employs the Buck-Boost charger BQ25713 for a wide input and output range for USB PD charging. The USB PD controller card (PMP40442) can configure the charger to run both charging or OTG via the same power path. The PMP40441/2 is compatible with PD2.0. It also demonstrates BQ25713’s capability to support PD’s Programmable Power Supply (PPS) standard. In the OTG direction (i.e. the power bank as a power source): the USB port can output a fixed USB PD voltage – 5/9/15/20 V and USB PD PPS voltage from 3.3 V to 5.9/11/21 V with smaller than 20 mV step. A USB-A port is also included as a dedicated OTG source.

The PMP40294 reference design is designed for a high capacity battery packs which requires more and more charging and discharging power. It can support a wide input voltgae (5~20V) from any adaptor and deliver the maximal charging current up to 3A to a 3S battery pack. By adopting the bi-directional buck-boost controller BQ25703A: the power stream can be flowed bidirectionally in the same power stage. In reverse mode: it can deliver 5/9/12/14.5/15/16/19/20V 3A from batteries to the port. The digital progemmability provides further extended functions as well.  

The TIDA-00759 TI Design uses nano-power operational amplifiers, comparators, and the SimpleLink™ ultra-low power 2.4GHz wireless microcontroller (MCU) platform to demonstrate a low power wireless motion detector implementation.  These technologies lead to an extremely long battery lif
