Tps51285brukt has 5V and 3.3V LDO ultra-low static (ulqt) and Dual Synchronous Step-Down Controllers, which are shipped at a preferential price
explain
Tps51285a and tps51285b are cost-effective dual channel Synchronous Step-Down Controllers with 5V and 3.3V LDO. This controller is aimed at the power solution of notebook computer system. This device uses automatic jump and ulq ™ Mode to achieve low power consumption, which is conducive to prolonged system standby
Battery life in mode. A 256khz vclk output is provided to drive an external charge pump to minimize power consumption in the main converter
A grid drive voltage is generated for the load switch.
The device adopts adaptive on time d-cap ™ Mode control, so as to realize fast load transient response without external compensation network. The input voltage range of tps51285a / b operating power supply is between 5V and 24V, and supports the output voltage of 5V and 3.3V. Tps51285a and tps51285b are 20 pin, 3mm x 3mm, QFN package, and the rated operating temperature is - 40 ° C to 85 ° C.
