Other Parts Discussed in Thread: TPS53015
https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/838607/tps53015-is-there-any-minimum-output-voltage-that-can-be-achieved-by-this-device
您好！
我计划使用 TPS53015获得5V 8A 输出、输入电压范围为5V 至17V。
您能否确认 TPS53015是否符合我的要求
TPS53015的典型关断时间为230ns、开关频率为500kHz。
关断时间将限制最大占空比并影响器件可运行的最小输入电压、并将输出调节至5V。
假设系统中没有损耗且典型关断时间为230ns、则保持稳压的最小电压为5.66V。
Vinmin=Vout/(1-fsw*toff)
5V 输入至5V 输出是否重要？
此致、
David
