TPS60204: About device difference

Part Number: TPS60204
Other Parts Discussed in Thread: TPS60200,

Hello Team,

Please tell me the difference between TPS60200/1 and TPS60204/5.
Looking at the internal block shown in the datasheet, it appears that there is a difference in the presence or absence of the auto discharge function. However, in the datasheet of TPS60204/5, there is an item called "Output capacitor auto discharge time" in electrical characteristics, and it seems that there is an auto discharge function.

Best regards,
Kato

    They are basically the same but the 04/05 can operate with lower input voltage, and the Iq is also lower. You are right the both can discharge the output capacitor. However, the 00/01 has an active discharge switch, and the 04/05 discharges through the VOUT sensing resistor divider.
